Guess What's In My Pants?

From OAPedia.com

Opie and Anthony game where a female listener rubs her phone over her pubic area, and the boys try to guess what type of hairstyle she has down there. Choices are mohawk/landing strip (rectangular patch of hair), Hitler mustache (smaller version of the mohawk/landing strip), 70's earth momma muff (big bush), the Jon-Benet/wood floor (clean shaven), or the 5 o'clock shadow (clean shaven but starting to grow back). Abbreviated GWIMP.
