nitty

Etymology 1

From nit + -y. The “foolish, inane” adjective sense is from nit (“fool, nitwit”), possibly under the influence of nutty (“crazy, mad”). The origin of the noun sense (“dope fiend, druggie”) is unknown, but could refer to a person who is under the influence of drugs to the extent that he or she is careless about personal hygiene and unkempt. Compare the verb nit (“to be a nitty”).

adj

1. (archaic, also figurative) Full of nits.

When I find a slut asleepe, I smuch her face if it be cleane; but if it be durty, I wash it in the next pisse-pot that I can finde: the balls I use to wash such sluts withal is a sows pancake or a pilgrimes salve.
