What does 'stuff a sock down there' mean?
That's the conversation in FRIENDS bwt Ross and Chandler in 7-13-They All Turn Thirty. I do not quite get the meaning.

Ross: How hot do I look in this, huh?
Chandler: oss, a sports car? Wouldn't it have been cheaper to just stuff a sock down there?
Ross: That's not what this is about, ok?

Answer

Haha.

What Chandler is implying is that Ross bought the sports car to compensate for a small penis. That´s why he suggests that it would have been cheaper to "stuff a sock" in his underwear instead.
