purple cheshire stripe

An act of wrapping a/your penis with fishing wire till it turns purple and swollen with the string making it look like the Cheshire cat from Alice In Wonderland.. (also known as the Purple Tiger)

If you don't watch yourself, I'm going to tie your d!ck into a purple cheshire stripe and leave you there...
M:Hey baby, check out my purple cheshire stripe.. W:OH DEAR GOD?!?!?! WHY?!?!?!?!
Patient:I tried the purple cheshire stripe and now it doesn't work... ERNurse: Dumbass... You don't leave it on overnight..
