Hot dogging - Usually reserved for when sex is an unavailable option. Simply put your dick between her ass checks and hump away. (A wiener between the buns)
"Sorry babe I'm on my period, but you can still do some Hot Dogging."
"Hot dog me like one of your french girls"
When a guy places and then thrusts his dick (hot dog) between a chick's ass cheeks (buns) - similar to titty fucking) - there is no penetration; just add mayo (cum); works best when the chick has a lot of "junk in the trunk"
