A variation on the words peng and boobs, meaning the owner of said poobs has a set of "Peng boobs".
Originating from
Nottingham, UK, where poobs are aplenty, boys regularly spy-out a nice looking lady and set about the task of
getting into her
underwear to discover just how peng their 'poobs' are.
Naomi - Wow, my boobs look great in this tight dress, the
cleavage comes up to my eyes!
Ben - They certainly are a
nice pair of poobs! (Stare)
Naomi - Why
thankyou!
