Sesame chicken describes a scrotum
peeking out of a guy's shorts. The coloring, texture, shape, and size of the visible portion of the scrotum is oddly similar to a piece of
sesame chicken from a Chinese restaurant.
This is not a flattering situation. It usually happens without the guy knowing about it. It is most common in
summertime, when the guy is (1) wearing boxers and (2) wearing loose fitting shorts.
Dude, I caught a
glimpse of your sesame chicken. Some things can't be
unseen bro.
For the love of God, cover thyself.
