back-whacker

A person in tight public spaces that seemingly has forgotten they have a back-pack on and whack everybody else with it.

back-dooral

Act in which a woman performs oral sex on a sex partner immediately after doing anal; thus giving her a brief yet adequate flavour sample of her own back door.

*She seemed pretty eager to try out a back-dooral; shame she barfed on tasting*

Back Canal

Another definition for the butt, usually in relation to anal sex as an alternative sex route.
