An abnormally large dreadlock that forms on one's taint by a mixture/combination of sweat, fecal matter, extralong-unkempt taint hair and extended walking.
Because I forgot to trim the 'hedge-row' on my taint, as a pre-emptive strike, before leaving for the show... 3hrs into walking around the grounds of WOODSTOCK '94, I had developed the most debilitating shitlock on my taint. With every step, it would twist tighter and tighter, through friction between my inner thighs/lower ass-cheeks... It was dreadful!
To render toilets out of order by blocking the hole either inadvertently with faeces or deliberately, i.e. in a state of relatively important intoxication, by adding whole toiletrolls and sometimes crockery
"The fucking idiots, they've shitlocked the bloody toilets !" (typical assessment on Saturday mornings in an English university hall of residence)
(pl. shitlocks)
Really fugly Dreadlock-type thing that results from either not taking good care of your hair, or trying to grow dreads and failing miserably.
The act of getting beligerant and shitting yourself. This is followed by taking off your drawers and putting them on your head like a hat, and then smearing shit all over the entire room you passed out in. Never clean up your mess, just leave the premises the following morning when you arise in your mess.
Man did you see the bathroom after that party ?!? someone shitlocked it !!!
