A law-breaking, unclean, over-intoxicated female. The type of mama who pops pharmies while carrying her passed outboyfriend through the lot like a cape, screaming, "Wake up, I just fed you my last roll!" Wears a sideways visor, possibly has dreads, almost always owns a large dog. She can be found scheming on Shakedown.
Did you see that schwilly mama at the Phil Lesh show last night? She passed out in her own vomit on the hood of my car.
Getting drunk and said drunk is usually all fired up and boisterious all the way up to cocky and feeling froggy. Sometimes getting Schwilly is used to describe to process of Schwilling on a bottle.
"Man I heard you got arrested the other night" "Yeah I got all fucking schwilly and swung on the bouncer" Or when a friend shows up with a bottle of booze and says " hey lets get schwilly"
