Shwap is alcoholic beverages (can be a singular or plural term); so, if youre going to buy some shwap, you're going on a beer run.
To BE shwapped, is to be extremely drunk.
New closely related words have been derived from it, including SHWAPTASTIC, a term used when someone does something fantastic when theyre drunk. it therefore becomes shwaptastic. Some people play with the word and say shwippity shwapped or other silly things. but you
get the picture. this word came from the wonderful city of
Manhattan Beach,
California. We are the founders :)
