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 :)
Kylee was so shwapped last night you should have seen what she did. i must say, it was shwaptastic.
shwapping involves taking items such as clothes you don't need or want anymore to a free shop(a place where no cash is exchanged), and you give way the clothes you don't want or need and in return have a look for and take clothes or items you either want or need.
