Rinnosaurus

Pronounded like Rin/Tyran(nosaurus)

(1)The word someone uses by mistake because they don't know the damn animal name is rinonasuras!

(2)They also give the excuse that a Rinnosaurus is an old ass Rino! It's so old its like a dinosaur!

Can you believe this man was stairing at my Ecco jeans talkin bout - is that a pink Rinnosaurus on your ass?
