Slappy

When you are really tired/hyper and you will laugh at just about anything. Named after the knee slapping laugh. A person who is "slappy" will slap their knees laughing over any joke, good, bad, or ugly.

Wow! that joke was really lame! Why is she laughing so hard?

It's because she's slappy tonight
