Lean Over 

A light hangover. Very similar to a hangover except you are not hanging, just leaning.

Keifer: "Dude, I feel a little hungover, I only had three beers."
Neal: "You're having a lean over, man. You're only halfway there, you might as well have gotten completely smashed."

lean Overdose

When someone drinks too much lean (a mix of codeine cough syrup and promethazine), causing their body to slow down dangerously — leading to nausea, confusion, slow breathing, or even coma and death. It’s not just “feeling sick,” it’s a medical emergency.

“Bro tried to flex with a double cup and ended up in the ER with a lean overdose — that stuff ain’t no joke.”

leanover 

A small-sized hangover, usually comes with merely a mild headache, a vague fatigue, and little or no sense of regret and/or shame.

I didn't really drink that much last night, but I think I've got a leanover. Wtf!

To give a person a blow job, as they are driving.

The slut gave leanovers for rides to the mall.

Leanover 

The equivalent of a hangover, but when you've been really lean the night before. Characterised by a lazy fatigue, forgetfulness, and a mild desire for another joint (See Wake n Bake.)

Man, I've a stonking leanover, think I might roll another today.
