The act of never-ending laughter that usually ends with an uncomfortable joke that is meant to continue the laughter, or when someone's mom gets hit by a car and dies.
"Dude, that joke made me sedlak up until Matt's mom got hit by that car and died."

"I told my mom a joke that made her sedlak, until she got hit by a car and died."

Get the sedlak mug.
When you buy a large share of stock, and sell it 5 minutes prior to the price increasing 50%+
I just sold Stock X and it just jumped up $30 a share. I really Sedlaked that one today.
