Top Definition
An action when a person of the male sex and a person of the female sex are naked and rubbing their genitalia against one another. This action is very similar and close to actual intercourse; however, there is no actual penetration. Rather, the male penis (hot dog) merely rubs against the female vagina (taco). Hot dog taco-ing could lead to pregnancy, so one must be smart and use protection.
a.)"Yo man, did you and Taylor have sex yet?"
"No bro, but we got close, we definitely did the ~hot dog taco-ing~."

b.)"Man, me and Emma did some hot dog taco-ing last night, and it felt soo good. I almost got in."
