Whaler

A man who goes for large and/or overweight women who generally have a massive top and bottom.

John is such a Whaler. He's dating that girl Katie who ate the plasma screen t.v.

Harpoon

To make love with an extremely overweight person(s) by entering her body.... just about anywhere you could find:
Dimples, rolls, clefts, jowls, over hang... well you get the idea.

Dude the whaler harpooned her in the shoulder.
I know... probably couldn't find her vagina.
