Sock

It's a sock. A thing that is probably on your foot now.

It can be whatever color you like.

You can buy it in shops.
You can wash it.
You can wash it in a washing machine.

I don't even know what to say!
Your dumbass actually doesn't know what a fucking sock is????

Just google it or whatever...

You actually didn't know what a sock was or you just wanted to look how people would describe it

Tell me the truth

Person 1: what are you wearing on your foots?
Person 2: socks
