Basically you cook up a real stinker in your colon, CUP your hands over your "exit-hole", let loose taking care not to 'spill' the contents, and waft/push/throw into your victims face so they get the full 'benefit'.
Then casually remind them that fart is made up of minute microscopic poo-particles and they have in fact, 'just eaten your shit'.

Cupcaking is the verb form of cupcake. Cupcaking involves paying more attention to a girl than your friends, usually through text-messaging or other means of technological communication. A person will usually be cupcaking when they are attempting to hook-up or flirt with a girl, due to the fact that cupcaking can be viewed as attempting to "warm the girl up."
