This is commonly British termanology for when the juices of a female come out of the vagina. This "vagina" produces flange batter during what is known as foreplay.

Flange batter is an excellent and completely natural source for the wetting of the vagina. This leaves the axe gash open and ready lubed up for a good session.
- Darling, you must have been horny tonight, your flange batter is all over my sheets. Wow thats wet!

- Angela, your flange batter tastes like jiblets, now go have a wash.
