When 2 men's body hair come into contact with each other and they get stuck together. (One man is hooks and the other loops)
I was sitting on the porch swing with Chad when our legs touched and we got Malercroed together."Malecro"

The unfortunate and unintended side effect of two hairy men sitting next to each other and becoming permanently attached.
As a result of Male-cro, if Robbin Williams and Tom Selleck ever did a movie together, they would be unable to film anything other than sequels for the rest of their careers.
