Top definition
After hearing a sentence, to note a word or phrase in it and change it (Or just look at it in a different way) to make it more disgusting/immature/, usually used in what would normally be a perfectly normal sentence and completely random and without warning. Often followed by everyone around the "Janosifier" groaning or sighing.
GIRL - "Yasy, it's Thursday tomorrow!"

BOY - "My name for Thursdays are Rape Days!" :D

...

GIRL - "You just had to fucking Janosify it again, didn't you"
