That's angle shooting and it's illegal in poker. Angling is any type of fraud. Because poker involves money, attempting to manipulate another player in any manner in order to make that person part with their money is fraudulent.
Poker is civilized game. Ethics and etiquette play a large part in poker and cheating, such as Angling and player deceit, will be quickly detected by Casinos (who have professionals watching many high resolution cameras in back rooms). Trying to fool other players will not be tolerated in a Casino. Such illegal activity (such as deliberate deceit) committed at a Casino's poker tables will usually result in a lifetime ban to player angling to gain unfair advantage for many reasons, including legislative and legal reasons (such as risk to their Casino gambling licenses).
Play your hand and use the information the game offers. Do not try to influence other players through fraudulent means to part with their money as that is not Poker, it's some other game that you are playing and those in charge will soon sniff out the lie and eject you from the game.
As an example, there was a recent 2017 PLO tourney where a player attempted to take advantage by convincing others he was inept. What this corrupt character did was he would put in calling chips while announcing "Raise." He then immediately says, "Sorry! Call!"
The problem is the cheater/angler knows the Floor/Tournament Director/Dealer will enforce his verbal "Raise" declaration as verbal declarations stand in poker. What this cheater/angler is trying to do, however, is appear weaker than he is by trying to suggest he never intended to to make the "raise" (thus committing to a minimum-raise) he has now verbally locked himself in to make. The other player sitting there now thinks, "This guy can't be all that strong, I'll call or even re-raise or even shove all-in."
So here's the rest of the story: The problem is this angle-shooter has been caught on numerous occasions doing this when he has the absolute stone-cold-nuts - an unbeatable hand. Casino's keep good records that they share with each other. A cheater/fraudster/angler will be well known everywhere if they are persistent in their cheating of other players. In this scenario, the angler/corrupt player has attempted to fabricate a story that his holdings are moderate or not strong and he is further selling the story as being the result of his incompetence - he's effectively deliberately lying to, and telling the other player, "I have modest holdings and in my incompetence I can't even get the words 'raise' and 'call' right." All the while, this fraudster/angler is holding a monster hand that would crush his opponent. In this case the Angler (who like the poster of the question here on this webpage wants to appear incompetent to gain advantage) is holding a Full House compared to his victim's two pair (including top-pair) hand.
Well, needless the say the Tournament Director is already aware of this angler and immediately steps in and warns everyone involved and watching of the angler/cheater's fraudulent intent. The angler/player receives a final warning later that he will be banned for life if he tries the behavior again against another customer of the Casino.

Bottom line, fraud is illegal, and both elements of fraud (money and deliberate deception) are present in your question's intention. If you want to cheat, poker isn't for you and in the wrong game, it can have serious life-altering consequences. Also, you have a gambling problem in that you think winning at poker is a foregone conclusion to the point you are so good you just have to trick others into staying at the tables.
