Cross between a squeal (of glee) and a tingle (due to encountered hotness) and possibly involving connotations of tinkle ('cause you're so excited that you sorta pee yourself a bit). Much like "squeal" and "tingle," skwinkle can be used as either a verb or a noun.
"Indiana Jones makes me skwinkle."

An action that one does when one is excited. Put your fingers to the sides of your nose and wiggle them while saying "YAY!"
