Logic: They have to work harder to keep their chick because they're not a 10, probably not even an 8. The less desired a guy is, the more appreciative of you he tends to be.
You feel skinny because you're the smaller half of the duo, duh.
So while swiping, give the chubby kid a chance.
Unless he's short, then definitely don't.
Short + Chubby = Stubby and that's just not hot.
Sorry not sorry,
