What is Lemon Meringue?
When a guy is fucking someone, comes inside them, stays in until he gets soft, and then pees in them.
Man, he was so drunk when we were doin' it last night, total lemon meringue before I could roll him off of me!
When a guy blows his load in a girls mouth and follows it with a stream of urine.
"I drank so much last night, then totally lemon meringued that girl."
