smiley motherfucker

Someone who smiles way too much to be a normal human. They are always happy even at six fucking am on the day that Hitler rises from the dead and carries out nine-eleven all over again. They are probably just an alien attempting to understand human behavior to know if we should be enslaved, destroyed or left alone. They are, however, well meaning so don't hurt them, I don't need earth getting destroyed because you punched a smiley motherfucker just because they were too happy.Someone who smiles way too much to be a normal human.

Try the ketchup motherfucker

This is a phrase widespread in the Linkin Park community. The phrase is a misheard lyric from the song “When they come for me” by Linkin Park, Where Mike Shinoda says “Try to catch up motherfucker”. Many people misheard this line as “Try the ketchup motherfucker”. It’s also comical with many people joking that they will try Mike Shinoda’s “ketchup” or Mike Shinoda “poisoned” the ketchup etc. The phrase is used randomly as it is in the song.

“Ok I will try the ketchup motherfucker”
