Squirt refers to the fluid

Squirting refers to the fluid expelled from the vagina during orgasm. Not everyone with a vagina squirts during orgasm, and those who do can only squirt occasionally. This type of orgasm includes a rapid ejection of urine from the bladder.

Squirts sometimes also involve secretions from the alkene gland. Skene's glands are sometimes called the female prostate because they function in the same way as the male prostate.
