Help solve a mystery!

I have been recieving mysteriously homoerotic text messages from a number I don't know, and after many hours of flexing my detective skills I can't figure out who this person is, so, someone and everyone should probably just call this fucker:

936 577 0633

Ask for "The Big Dog."

He lives in Huntsville, TX. That ought to make the search smaller. Do you live in Texas too? I live in one of the states above you if you do.
