Inserting four fingers into your friendly neighborhood cheerleader (you know they can take it) and then spreading your fingers, screaming "School Spirit" and throwing glitter at his/her face. The ladies love this slightly tender and romantic gesture of selfless love making. The homos think it's hilarious because they can't feel a thing.
Chelsey loves it when Chad spirit fingers her at the dinner table.
Craig loves it when Brad spirit fingers him while they discuss Cuban poetry and eat bon-bons.
Discussing spirit fingers with your mom/grandma can be awkward (because they know they want it and it shows).
