adj. (1) this word describes the state of someone who becomes somewhat giddy or abnormal in behavior as a result of being smacked around. It is thus synonymous with punch drunk.
(2) it has also been used to describe a person with a penchant or delight in hitting others, but this is certainly not a noun that refers to the state of happiness produced by the hitting.
You can tell that boxer was slap-happy in his post-fight interview.
That bitch, Jennifer, she sure is slap-happy. But I guess it's usually good when a girl hits you.

Get the slap-happy mug.
When a girl is deepthroating you, you slap her after she spits out a lot of flem. This comes in handy when the girl bites your dick so you just slap them to make them not to it as often. Slapping them gently makes them laugh and also builds up more spit.
I was deepthroating but my cock on her face then I slapped her gently. This gathered more spit from her mouth which made deepthroating more interesting. This is called a slap happy deepthroat!

laughing in such an uncontrollable way that if your friend was to slap you in the face it wouldnt phase you. also, if one becomes "slap happy" it is extremely difficult for those surrounding him to control their laughter.

when you get too carried away with slapping a person or persons.
It could just be that you went on a slapping spree (greatly encouraged by me by the way, they're fun!)
or that you got so pissed off with someone that you just physically couldn't stop slapping them.

Get the Slap Happy mug.
When someone's been in a fight and they've been hit in the head so much that it makes them act silly and crazy. Sort of like punch drunk.
