A rather vulgar terminology for the female anatomy, more specifically, the vagina; however, it is also used in the context of makeshift possession (i.e. getting tud).
"Ayo nigga, Pinky got some sweet tud, son."-Justin
an object composed of fecal matter entwined with toilet paper that is rolled into small balls and caught in the hair lining the greater butthole region.
Dude, I got some Mexican food the other day... I was finding tuds for a straight week.
