a combination of the words slut,
cunt, bitch, and also
bag, because
bag just makes every word ten times better. Usually used as a nickname for complete badasses, or to describe the lowliest of lows.
"I was talking to
Dana yesterday, that scuntchbag that works in town. She's such a
badass, Chuck Norris had her sign his shirt."
OR
"
Ugh, I can't believe that scuntchbag tried to talk to me. She just smells like a walking STD."
