look up any word, like darude - sandstorm:
An excuse used to blow off girlfriends that have been wondering where you've been and why you haven't called, when in fact you've been locked up in the house with your boyfriend and have been too "occupied" to even pick up the phone when it rings
Chick 1: Hey, where've you been...what's up?

Chick 2: I'm just so BusyTired
