An unfortunate or surprise bowel movement that someone finds upon waking, usually after a hard night of drinking or experimentation with laxatives and/or bad mexican food.
Dude. After eating at Paco's last night, my stomach felt a little funny. And when I woke up this morning, I found a bedbrownie!
1. At a wedding instead of Smashing cake into the bride or groom's face somebody comes up with an actual turd uses that.
2.On a night after attending a wedding when a guy or a girl has someone poop on their face and rub it in. Not necessarily a member of the wedding party could be anybody that attended the wedding.
3. Similar to a Cleveland steamer except rubbed in one's face instead of their chest.
4. An actual brownie made from Cannabutter and giving as a treat at a wedding.
Damn did you hear what Stephanie gave Matt after that wedding? No what was it? She gave him a wedding brownie!
