When you eat a noodle and it comes out the other end (butthole) purple.
Happened to me before, true story.
The colour is a common purple like a royal purple (look it up)
Pronunciation*
Woh-sk
Guy 1: hey Jimmy, wōsk that noodle!
Herd of dudes: wōsK It, Wōsk IT, wōsK iT!!!
Jimmy: I am, I have successfully wōsked the noodle!!
Random Srag in backround: *points at Jimmy's butthole* hey gang, look at Jims but, the noodle is coming out purple! Delicious!
