Under-carriage munching

A term coined by a cool Aussie chick used to describe when koalas go downtown on each other.

‘Hey Davey, koalas are cute but most of them have Chlamydia. Probably from all their under-carriage munching.’
‘It sounds fucking sickening.’
‘It is fucking sickening Davey, it is.’

One step above an alpha male.
