look up any word, like cunt:
1. A dog's penis; what a manly dog places in his girlfriend to make furry dog pups
2. An asshole, idiot, fool, douchebag, or prick
1. The dog mounted his bitch, inserted his dognis, and began to thrust
2. Dude, don't be a dognis!

**Don't you ever touch my dog's 'nis!**
