biranosaurusfucktard 

Someone who you just absolutely fuckin hate. A person who constantly goes behind your back and keeps stabbing you. Actually you can just call anyone this out of pure hatred and it is gauranteed to make you or the surrounding people laugh. Also if someone just make a completely dumbass mistake........who the fuck am i kidding the name explains itself just call someone it and your day will be better. If you are smart enough you will know the right time and place to use this. So i am actually wasting my time with this stupid fuckin definition
