Ginch Gonch 

A brand of very expensive underwear, about 30 dollars a pair with designs on them, 25 for 'basic'. For both men and women. Some of their designs have very sexual connotations (wiener eater, ass licker, piggy bottoms, beaver eater, shooting stars, ect.) Pretty much not available anywhere but online. Very colorful. They try and mimic youthfulness, and the result is underwear so playful it's barely sexy.

"Your underwear has pictures of hockey players?"
"Yeah, wanna fuck?"
"Not if you aren't wearing Ginch Gonch. Bright colors turn me on!"
