When having sex with your girlfriend from behind she swallows a bit of bacon rhine on a string, and just before you cum you pull on the string making her gag forcing her to tighten up all her vagina muscles making for intense pleasure.
Last night i was shagging the miss and we tried fetching, best thing i ever done, she was only a little sick on the pillow.
An act of sexual pleasure between two or more homosexual men in wich one cums in another anus. He then puts his lips to orifice and sucks out the cum/shit and spits it into the firsts mans ass, who then swallows with glee
Taken from "Monty Python and the Holy Grail", to fetch the cow is to react disproportionately and inappropriately over a very small insult or slight. Can also be shortened to simply "fetching".
Man 1: Your scarf's quite gay.
Man 2: Say's you, fucking homo, I hate you. Your mum's sucking my cock every night, and I'm wearing this fucking scarf when she does it.
Man 1: Mate, stop fetching the cow.
