Slavering horny adolescent male 1: I'd hit that.
SHAM 2: I'd hit that like the fist of an angry god.
SHAM 3: I'd hit that so hard, whoever could pull me out would be the king of England.
Formerly a slang phrase referring to a male's stated prediliction toward sexual relations with a previously identified female, the phrase has now come to refer to an individual's stated desire to perform sexual relations with a (typically McDonald's) hamburger.
Background: An unfortunate McDonald's advertising campaign, circa early 2005, developed under the assumption that the use of urban lexicon might appeal to a previously underrepresented demographic, i.e., the burger-fetishists.
"Double Cheeseburger? I'd hit it. I'm a Dollar Menu guy."
