Something you should always yell when you do something sudden. Also good to apply when making contact to someones face with your fist, or delivering a snappy insult. Funny word, I thought I'd share it with you.
"ZWANG!"
"Yeah he gave me some lip so I zwanged him in the face"
Zwanging is when one is high of codeine(cough mixture) and and xanex as the feeling of codeine makes you feel like you hanging,(or modernly described as leaning)
The Z in zwanging is derived from the pronunciation of the word xannex.
ie I cant even seestraight thats how hard Im zwanging.
