When a fat man loses a lot of weight and no longer sees the tip of the iceberg, but the entirety of it. (The iceberg being the penis in this case)
Soon after the male engages into sexual intercourse and plows a female's vagina vigorously until her hull explodes from the impact.

A common sexual position between a newly slimmed down fat man and a ready and willing female ready to release her fluids from the raw impact of the iceberg.

Penetrating her with the iceberg coincides with the iceberg penetrating the hull of the Titanic which is why this sexual position is called "Sinking the Titanic"
"Hey Paul, how was it losing all that weight?"

"Great, I was sinking the titanic with my girlfriend last night.
