A mixture of lean and molly. Gets you fucked up. Once on the semmy, you can’t get off the semmy.

Semmy

Short term for a semester. Most often coined by someone who watches nelk boys, hockey, or is a frat bro. It uses the same term logic as calling a celebration a “celly”.

“I am so hyped for this semmy! The parties and sorority girls are gonna be hot as shit man!”
