A girl that's too ugly to be seen in public with. Also see Basketball hoop and Park Bench
Random Person:"What happened at that party?"
Yourself: "There was only guys and a bunch of rocks there so I left."
Rocks are like bones. If you 'Give Rocks' for example, it means you don't give a shit. It's like giving bones. Like Senator John Fetterman doesn't give rocks for the Pro-Hamas crew in Team Blue. Dopey Fetterman gives Rocks for the squad and the Democratic wrecking crew. He's on Team Israel and he's rocking off the back foot!
Senator Fetterman gives Rocks for the opinions of the Democratic Squad on their anti-Semitic positions. He stands proudly with team Israel. The anti-Semitic squad believes he's brain-damaged for supporting Israel. Go figure!
