Fat Block 

Denying women to a fat kid, who would probably have sex with a fat kid. This is similar to cock blocking. This act should be avoided at all costs. Unless you want to be a d-bag. Allow your fat friend to get some, it's a beautiful thing.

This hot chick said that she would have sex with my fat friend, which was awesome, but my other "friend" cut in on the action commiting the sin of Fat Blocking.
