Every Thursday, meat lovers come together to cram themselves with as much meat as physically possible. Typically eating shit loads of Italian BMT's from Subway, Sausage Rolls and anything which is probably not that good for you but gives you a warm feeling inside.
Person 1 "Dude, are you taking part in Meat-Thursday this week?".
Person 2 "Hell yeah! I just love that meat in my mouth!".
