your nan is gay!

used when u cant hear someone and cant be bothered to ask them wtf they were on about.

my OC's using this word lol

Illie: Yo so basically i sent a bucket of creamy water to Turkey and Amazon delivered 4 vibrators to a South American chicken which gave birth to the entire earth which is why myths exist-
Draggy The Dragon: your nan is gay! shut up! no one cares!

shag the dog

shag = screw aka screw your imaginary gf who is actually an anime character with big tiddies
so basically screw a dog
and say when ur bored or out of context
or maybe sarcasm

friend 1 = 'hey its time to wake up!'
me = 'no its time to shag the dog'
