When someone leaves their social media account open, thereby allowing anyone (a friend, relative or co-worker) to post a status or tweet about their taking a crap.
"Dude, what was with your status last night?"
"It wasn't me, I swear. I was craphacked."
n. synonymous with "poopsack" which literally translates as the fabric suspended underneath the backside of a horse or donkey leading a carriage, preventing excrement from desecrating the public streets.
Alternatively used as an expression of disbelief, disappointment (usually in the plural form), or as an adjective to describe one's behavior.
