Code for "I <3 boobs." Taken from the famous "Saturday Night Live" Celebrity Jeopardy sketch featuring Darrell Hammond as Sean Connery. His answer for Final Jeopardy was "indoors" in response to the question "Where are you right now?" Connery's wager revealed lines transforming the phrase into "I <3 boobs."
Alex Trebek (Will Ferrell): Mr. Connery, where are you right now? You wrote... Good, Lord, you wrote "indoors." That's phenomenal. Are we recording this? OK, let's look at your wager. "I heart boobs." That's beautiful. That's it for Celebrity Jeopardy. I'm going home and putting a gun in my mouth. Good day.
Used to mean "she/he/you is/are very attractive and I would very much enjoy making love to you." It is derived from "A Night at the Roxbury"
