Urban Dictionary is a website full of crappy definitions of random words. Anyone can post the meanings of words and those definitions are usually based on memes or implying sexual words/meanings.
*a long conversation between a girl and her dumb ex*
Boy: Where do you find all those crappy meanings of words?
Girl: Didn't I already tell you a few seconds ago? OR DO YOU HAVE SHORT-TERM MEMORY LOSS?
Boy: Of course not! But how did you find that sentence? The one that described me so well? That same place?
Girl: I found them on Urban Dictionary, duh. WHAT DO YOU THINK? DO YOU THINK I FOUND THEM IN YOUR MATH TEXTBOOK?
Boy: How are those definitions defining me like CRAZY?
Girl: WHY WOULD YOU NOT KNOW? UGH. YOU ARE AN IDIOT. I SHOULDN'T HAVE TALKED TO YOU THE FIRST TIME WE MET. I NEVER LOVED YOU, JUST IN CASE YOU DIDN'T KNOW!
*Now read the whole thing backwards (starting from 'WHY WOULD YOU NOT KNOW?') LMAO <3
