Slang for when a girl/women fingers/ uses a sexual toy on her vagina whilst "
wet". This is because it is the comical '
sound' a vagina makes while under pleasure/ "
wet".
Yea, I bet she enjoys a bit of a splitch every
now and then.
She splitched herself last night,
maybe she was
lonely.
I was woken up by my mother's spltiching last night.
