A sexual act in which two women (or men, whatever the preference) simultaneously jerk off an erect male using both of their asses with the penis in between the four ass cheeks, long-ways along both ass cracks. Kind of like a two-bunned hotdog.

Similar to ass job (first definition), but with two asses; much easier to perform.

A person with an outwardly dominant, masculine, or aggressive personality, but who also enthusiastically takes on the submissive or "bottom" role in the bedroom.
