Stone Hammer

A lesbian who possesses very strong, man like tendencies. Such as cutting their own hair very short, stands like a man, and may even date/use a man simply to learn first hand how to look more like a man. Warning signs are the gingham patterned flannel shirts, with or without sleeves, trucker hats, or trigglypuff hair poof in addition to buzz cut side hair. Similar examples would be; butch dyke, bull dyke, G.I. Joe Jane, SJW with macho man flair, manly smirks.
May have even dressed as Harry Potter as a child even when it wasn't Halloween. Look for these warning signs.

"Bet you can't pick out Matt's girlfriend just by looking at the marketing photo of last years staff cookout."

Reply: "Yes, I can, its the stone hammer standing next to all the guys in the middle. Dead giveaway is no heels, no dress, no makeup, cop buzzed hair cut and rolled up sleeves." That's a typical stone hammer bro.
