Girl A- I was partying last night at this frat and I blacked out while hanging with this frat bro. The next morning I found out he tucked me in, gave me water, and smoked a joint until I awoke to see if I was alright.
Girl B- Wow, what a manbro!
Girl A- Why are you so happy today?
Girl B- This really cute guy held the door open for me and helped carry my stuff up while he was drinking a six-pack.
Girl A- Sounds like a manbro to me.
