The region between the balls and the arse-hole; can be an
erogenous zone for some.
Girl: 'I was fingering that part between his balls and his arse and there was shit there.'
Everyone
listening remained silent but later laughed among themselves:
'Eww! He had a shitty chad.'
When you measure your dick, don't start at the arse-hole and include the chad; you risk
getting shit on your measuring tape.
