Crap happens. Crappens is a blend of
crap and happens and is more indifferent,
lazy and quicker to say than "shit happens". Crappens has the added bonus of making the listener ask you what you said which usually pulls them out of their whine.
Whiner: Oh
man, I can'
t believe blah, blah blah...
Disinterested listener: Meh, crappens.
