A Hotdog Huddle is when a group of men, usually 3 to 7, are standing with their penises out, circled around a woman, who will be subject to bukake shortly thereafter.
#1: Man, that bitch was such a freak last night!
#2: The one that we did the Hotdog Huddle to?
#1: Yeah, bro. That bitch was a total freak.
