Piece of Scumbag 

An individual who does not quite possess the capabilities of a contemptible full blown scumbag and is therefore referred to as a Piece of Scumbag (POSB). It is often feared that POSB's will realise their full potential and evolve into their more powerful form.

Scumbag Steve

The counterpart to the internet meme 'Good Guy Greg', Scumbag Steve represents the lowest of lowlives. Appearing on Reddit, 4chan, and other internet meme sites, this meme features a drunk-flush man in brown clothing with his trademark brown-plaid hat. Over the picture go words telling of the nefarious deeds Scumbag Steve is known for - 'borrowing' your clothes and never returning them, using all your shampoo when showering at your place, answering your texts when you leave your phone unattended, etc.
Everyone has at least one Scumbag Steve in their life.

Scumbag Steve - borrows your car; gets it impounded.

Scumbag Steve - takes you for a birthday dinner; makes you pick up the bill.

Scumbag Steve - hangs over at your place; eats all your food.
