fake-ass definition
A trend among some Tumblr users where they invent a dumb definition for their URL and pretend someone on Urban Dictionary actually posted it. Usually they sound very narcissistic and is quite obvious that they were made by none other than the person who posted them. Most of the other users can't stand them and actively make fun of them.
Person #1: Hey, have you seen what somebody wrote about that Tumblr user on Urban Dictionary?
Person #2: That's clearly such a fake-ass definition, like no one would ever say that about them without being paid or seriously obsessed!
