A colloquial expression, usually used in (but not limited to) Australia and similar/English speaking nations, for the process of defecation. Generally associated with humans and other humanoids, this phrase can be also be used to describe the defecation procedure of other animals eg. the family pet. A similar, slightly less descriptive version is the phrase back one out. Note that the word greaser has a wide range of usage in other contexts.

big old greaser

A big old greaser is the ultimate being when it comes to unhealthy turds. It usually rates itself between 6 and 7 on the Bristol Stool Scale, and is the product of last night's low quality takeaway kebab. It has the consistency of somewhere between mushy peas and oily fish. It has the smell of any other shit, but its scent has a way of etching itself into your skin and clothes.

Person 1: Oh my god, what's that smell?
Person 2: I think that Bob may have let a big old greaser go in the bathroom?
Person 1: Classic Bob
