Usually someone who is incredibly strong. Maybe no upper body strength but man can she fucking hit a bitch.
Damn did you see Sarah last night she’s such a fucking tank
George: Man, I haven’t gotten laid in a week. My tanks are gettin’ full.
Dave: Better go rub one out and empty those bad boys.
Tank is a very hot male or female. They are very mean at first until you get to know them better and they will be one of the funniest people you know! But they will beat anyone’s ass so stay away from them if you have bad intentions.
Thanking another person in a toddler-like voice
Girlfriend: “I went grocery shopping for us!”
Boyfriend: “..Tanks”
