lady bro
A lady bro is a bro's girlfriend who's smart, tough, and can hang out with the bros without being a total pain in the ass.
'She came to bro-night, drank bro-sodas, and still beat me in a dirt bike race. That’s a lady bro.'
'She’s chill, she’s smart, and she doesn’t smoke weed. She’s the kind of girl who shows up and makes the bros look bad.'
'She’s not just a bro’s girlfriend. She’s a full-time bro and she knows it.'
