When you’re fucking a girl and your balls get itchy, so you drag them along the bed like a snail, while still inside of the girl.

1. To itch as if covered in nits

2. To itch after talking about nits, or other small parasitic insects, because you're now imagining definition 1.
3. To see another creature scratch and then feeling itchy yourself as definition 1.
4. To hear another person talk about definition 1. and then feeling definition 1.

5. Me right now
I was talking about someone at school who got nits and now I'm hella nitchy
