Substance released in the form of a bullet (in shape and size) as a person squats on top of his/her partner's face; may be fruity in flavour - depends on what materials have been consumed by the kumquatter earlier.
Alternatively, a fruit of the Chinese Orange kind.
Guy 1: Man, last night I let out a couple of kumquats on her face, and I had eaten a couple of oranges earlier so she started choking - she's allergic to oranges.
Guy 2: Oh no, what happened?!
Guy 1: She died.

Kumquat
It's when you start doing a squat but then realise that your penis is leaking cum, or there is juice leaking from your kunt.
guy: Hey baby, you better start doing squats more often if you want a great ass!
girl: Ohh.. I can't.. remember last time, you know I get kumquats when that happens!
