Scrum
Simply, the asshole. The butthole part of the whole ass.
Tim enjoys his scrum being eaten but Christine refuses to eat Tim's scrum because it is far too swampy.

Josh enjoys having his scrum pleasured orally quite regularly.

Shit comes out of the scrum of the as therefore some people do not like to put their mouth near it let alone eat the scrum.

Tims scrum smells like shit and is dense wet and hairy much like a swamp.
