Widely-acclaimed anonymous author of infamous wit and wisdom written on the stalls and walls of many bathrooms. The "Shithouse Poet" is believed to actually be a number of different individuals acting in nearly every state of the United States. Much to the chagrin of janitors, the Shithouse Poet leaves his nuggets (pardon the pun) of wit and wisdom in the form of well-crafted prose and poetry through various means in batrhooms throughout the U.S.A.

UK usage-

A very big person, normally male who is as broad as he is tall yet carries very little fat. Not the sort of person you would willingly upset.

Term comes from the large brick built outside toilets once common in working class areas of the UK.
