its kinda like cuddling, except a fadoodle happens much faster and is usually far more sexual. in cuddling, you kinda just sit there and snuggle, but in a fadoodle, you go straight for the business.
Dude, you just got fadoodled!
I am about to fadoodle you.
Dude, Johnathan came out of no where and fadoodled the crap out of you.
