What it means: You'll use this when you're dying for the toilet or equally for when you're dying for someone to just go away. When to use it: When your boyfriend asks you to go down on him for the fifth time in one weekend and you didn't really enjoy it the first time but now he has his hands on your head, subtly pushing you down to his crotch. "P*ss off you cretin!" Where it came from: The word wasn't used as an adjective until the Second World War where p*ss poor or p*ss it became common phrases, but it was known as a noun from the 1400s. Before that, in the 1300s, it was used as a verb, 'to pee', derived from the French language 'pissier', 'to urinate.'
