Catfishing is defined by wikipedia as

a deceptive activity in which a person creates a fictional persona or fake identity on a social networking service, usually targeting a specific victim. The practice may be used for financial gain, to compromise a victim in some way, as a way to intentionally upset a victim, or for wish fulfillment.

OP made an account on Tinder and pretended to be a hot guy by utilizing the image of a totally different, super attractive man, for the purpose of exploiting women and manipulating them into being at a particular place at a particular time so he could make it seem like the person they matched with stood them up, only to show up as a less enticing backup option to someone who was emotionally compromised. I mean, he obviously didn't because none of this is real, but if he had, it would still be catfishing.
