to
fetch the cow
verb
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.
