sweater chest 

A chest that is so hairy, you can't tell whether someone is topless or wearing a sweater.

I told Lance to take off his top so we could go swimming, but he said he already did. Damn that sweater chest really fooled me.

Chest sweater 

Similar to bear wings but on the front. Hair on a mans chest and torso that makes it look like he is wearing a sweater even though his shirt is off.

Wow are you wearing a chest sweater?

That's quite the chest sweater bob.

Sweaterchest 

A torso covered with thick enough hair that it could be mistaken for a sweater. In extreme cases, may be an extension of the neckbeard.

Robin Williams: total sweaterchest!
