look up any word, like fuck boy:
The act of not exactly sitting, but not exactly standing over a LONGDROP, but more a case of just bending the knees with your bum a few inches above the seat when wanting to defecate
The longdrop was somewhat very dirty, so I had to lavitate while trying to have a crap.

To use the toilet.
I've got to go to the bathroom to lavitate.
