What is Shitlock?
1.
An abnormally large dreadlock that forms on one's taint by a mixture/combination of sweat, fecal matter, extra long-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!
