Someone who likes to fuck fat girls/boys instead of normal sized people. For some it is a mental disorder; for others he person is just bad at meeting people and so they fetishize obeasts since they have low self-esteem and are an easy ride.
Our boy Andre has been rejected so many times that he has been reduced to a chubby chaser. It's even funnier since he is always trying to hide those land whales from his boys
Although this particular chubby chaser was plump himself, he still ran like a squirrel up to the top of the tree to save the morbidly obese woman. Understanding that his heroic character would draw this unhealthy, yet irresistible woman into his life, gave him all the courage he needed. There was no doubt in his mind that the woman of his dreams, now on safe ground, would wind up with the most brave chubby chaser of them all: himself.
