What is Ibbiacohintnw?
1.
Abbreviation of 'I'll be back in a couple of hours if not try next week' which means the speaker will be gone quite a while longer than 'BRB' suggests, therefore a longer absence needs a longer abbreviation.
"I've gotta go brush my teeth, get dressed, wake my baby brother up, make dinner, have dinner, go out to an all night party and then - well, basically IBBIACOHINTNW."
