-acronym, what I did to your mom
An acronym of the phrase “I Totally Hacksawed Your Mom's Ass Last Night”. The phrase has most recently been popularized in internet parodies of G.I. JOE Public Service announcements and often is text messaged as an insult between friends.
Hacksaw is sometimes substituted with jack-hammered, jigsawed, waxed, or polished.
