A guy into obese women.

They generally love to fuck any roll of fat they find on a women. Do not be surprised if you spot them playing with back-fat like they would boobs. If they cannot find a vagina they will most likely try to stick their penis in the general area of where said vagina is meant to be. If the blubber lover is a smaller man, the woman will be the dominant force in the act of making love. Be careful around blubber lovers, for they will take serious offense to any joke made toward fat people. They WILL call you shallow and constantly talk about personality over looks if you roast them. Before accusing someone of the act of loving blubber make sure they are not dating a fat woman out of desperation.
