The act of performing a standard tea bag while the person giving the tea bagging hums their favorite song. This resonates a orgasmatic stimulus to the recipient. Popular songs and nursery rhymes are always a favorite.

After a night of drinking Sally came over to my place and she gave the best humming tea bag ever to a great rendition of the Star Spangled Banner. God Bless America!
