Whilst performing sexual intercourse, in the Doggie Style position, the non-receiving partner lubes up his/her hand and rabbit punches the receiving partner's anus. With luck, the fist will slide in, and be rapidly retracted, causing the receiving partner to gape. The non-receiving partner then quickly spins 180 degrees, and takes a rotten dump into the receiving partner's rectum.

Feb 27 Word of the Day
From STEM, an abbreviation short for "Science, Technology, Engineering and Mathematics", a STEMlord is a pejorative term for a particular kind of person who has studied in these areas at university or works in these fields who holds a pretentious, condescending attitude to anyone who has studied in any other fields, particularly the Arts and Humanities. They typically believe themselves to be more "intelligent" and "rational", while generally remaining incredibly ignorant outside of their areas of expertise and having the charisma of a rotting pig's backside.
