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.

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."

leapover

n. A rare phenomena, similar in severity to a hangover, but occurring on the second day after heavy drinking with a strangely deceiving, asymptomatic day in between.

Ralph was power-drinking at the party on Friday night to the point where he almost passed out. He was up early on Saturday claiming no ill effects, only to suffer a debilitating leapover all day Sunday.
