BLT is an acronym that originated in NYC and it is what you call getting or giving oral sex in the back of a cab. It stands for Backseat Love in a Taxi. It was researched extensively and, to date, there is no slang term that defines such an action.
Oh shit, I met a really cute guy last night and ended up getting the hottest BLT ever on my way back to Brooklyn!
