When a guy puts his balls in his sexee's mouth and the girls expression is what she would look like if she were yodleing.
usually takes place during math class when the teacher is unconscious
kid: mommy, what did you do on your vacation?
mom: well honey, i met these great guys and we yodeled all day and night for the whole week i was gone!
kid: wow that must have been fun! does your throat hurt from all that yelling?
mom:no, but my tongue does!
kid:?! huh? what does that have to do with yodeling?
