The exquisite act of swallowing a hot dog whole and passing it through the digestive tract to the anus where it is released by the sphincter and then sucked back into anus. For a more homoerotic experience some choose to cook the hot dog till it's nice and plump and then freeze it solid in it's plump state. This gives the hot dog the feeling of a thick erect penis when it is being sucked back into the anus.
Me: How come I have 8 buns but only 4 hot dogs?
Red: I used some earlier, I saw them and couldn't resist doing a few quick habanero buttsuckers.
Me: I was going to grill those!!!
Red: You still can.
