bogmonster 

A member of the one of the British Ministry of Defence's covert special ops units, apparently originally named after their service in the 'Bogside' area of Derry, Northern Ireland during the troubles there. Known to have seen service in the middle east, Iraq and Afghanistan.

Reputed to have used baseball bats and swords & hammers during close quarter attacks to remove hard core IRA units rather than using firearms and having a reputation even amongst IRA units as ultra-violent with no apparent chain of command.

bog monster

A bowel movement (typically at least partially formed) that causes smoky looking steam or vapor to rise from the bowl. The visual is similar to a creature in a foggy bog or marsh in a sci-fi or horror movie.

I am never going to another one of your barbeques. All that Natty Ice, and chili, and hot wings had me birthing a bog monster the next day.
