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.
1. when john wasnt looking, i took a drink of his cup and when he finally noticed 10 minutes later, i became slap happy.
2. hey rich, i'm fucking slap happy. (rich in turn becomes slap happy)
