a singular word expressing appreciation of an amusing physical action.

I took to saying it to my bulldog and pitbull in appreciation of their leaping on the kitchen table or doing something otherwise physically dramatic. Such as falling off the couch. I believe I picked it up from Homer Simpson.

It'd be quite cool if the "American Indian" history is accurate.

Cowabunga is a slang term of surprise. It is incorrectly credited as becoming part of the lexicon when it appeared in the Ninja Turtle movies in the early 1990s. In fact this word dates back to 1964 when it was first heard in the movie "Pajama Party".

Basically the male version of the shocker. When a female forms a cowabunga sign with her hand and simultaneously jerks him off while sticking a thumb in and out of his butt using the SAME hand.
