the act of unecessary and or excessive non-sensical word flow generated by females at a quick and unconsious pace. The origin of the flapping is the vagina.
if one is to commit a flap doodle, they would be flap doodling. Flap doodling is to participate in an act that your parents would not aprove of. i.e. sex, drugs, alcohol, wacking off etc.
"I will let you have your flap doodle now... but next time, let me be clear, there will be no flap doodling on my flap doodle time!"
The word takes its name from the innuendo between 'Kat' and 'Pussy'.
Also for those who don't mind getting freaky and going downtown, a bit of pussy licking is as tasty as eating a KitKat!!
'Yo my bwoi Rob knows how to nibble dat KitKat Flap'
