Cockmuffin

A cockmuffin is made after obtaining a muffin and rubbing your penis (and balls perhaps) and give it to someone, in the hope that they will eat it.
If one eats it, it will result in a huge comical effect and everyone will laugh at the person who consumed the cockmuffin.

1. Creating a muffin when your friend's back is turned and saying something like, "here have this perfectly normal muffin" and they will inevitably eat it straight after offering it to them. Then the inhumane, humour will commence.

2. I accidently dropped a muffin on my wiener, now it's nothing more than a cockmuffin.

3. I just baked a whole batch of cockmuffins for all the neighbours children to eat.
