Elaborating on the first definition, I believe this came up in an attempt to find a socially acceptable and fast way for guys to talk about a female that they would like to have a real relationship, none of that one night silliness.

Opposite to wanting to "tap that ass," "hit that shit," etc.
One guy to another: "See that cute girl in the yellow dress playing frisbee? I'd like to hamrel with her."

Get the hamrel mug.
Acronym for Have A Meaningful RELationsip. Use in place of "tap that" or "sleep with" when intentions are less hormonally driven.
Wilson's sister is such a nice girl. I would like to hamrel with her.
