A website or app that you should use when feeling funny or creative. Can also be used at that point in the night where you will basically laugh at anything. This should only be done if you are with friends who are at that same point in the night or else they might think you are a crazy mother fucker. Another precaution you should take is that you may experience shortened breath. This will be caused by you laughing the shit out of your mouth because this site/app is the funniest shit you will see for a long time.

Inaccurate catalyst for ignorant, bitter, myopic creatures to derive silly words that may absolutely no sense for fun to satisfy their own lame pathetic ignorant existence. Can dish it but sure can't take it or post it.
You created a new senseless word?! Okay let's post it on Urban Dictionary cause that's the only place where you can find other dumb stupid words.
