a comical yet serious and angry outburst for no reason in the middle of an assembly hall or public toilet
harold: Damn did you hear about what edward done in the assembly hall :O
simonson: no what:O
terrance: do tell
harold: well i heard from benjerman that he pulled down his trousers and shouted "nedips" at the top of his voice
nicholas: jesus christmas:O that wasnt wise, i heard that the head teachers a perve:O
benjerman: did he get caught?
thomas: no he has nedipsitis and the teachers had to let him continue his outburst which turned into a rather nice rap battle at the end
