|1.||Sit this one out|
Popular Brit vernacular used when you just can't face taking part in something. First used in days of yore when people sat at the sides to miss a particular dance. Now it's used to skip meetings, when you're too drunk to dance with an ugly woman, or maybe skipping out on a party you know will suck weapon's grade ass.
"Dave, are you coming to Mike's birthday tonight?"
"Sorry mate, but he's a friendless loser, and I shagged his girlfriend. I think I'll Sit this one out, if that's alright with you".
"No worries fella."
