2.Stupid overly-patriotic american blowjob in which the unfortunate female (or often male) to be subjected to the tedious and mundane task of first finding the man's tiny cock under the mass of flab then puts it in their mouth and sucks it whilst humming the star spangled banner, causing the tiny vibration in his or her lips to increase the pleasure induced by roughly 0.000000001%.
2. How apt is this - the act of singing the American national anthem while sucking a fat man's cock and making him ejaculate all over your face. God bless America.
2. A blowjob when the girl hums on your penis
Jordan: Nothing much. What about you?
Cara: Oh nothing, I just got a brand new Hummer H2.
Jordan: Oh, cool. You know, that thing is a gas guzzler, so, to pay for gas, you're gonna have to give Hummers to guys for money.
Cara: Ummmm... ok... so-
Jordan: Here's 20 dollars. Now give me a Hummer.
It looks OK on the outside but it's just another hummer.
2) An act of fellatio in which the woman hums while performing.
I received a hummer last night and reached climax rather quickly.
