"In this case, semantics that you're trying to hide behind to cover the fact that your desire to be a smartass in this case overshadowed your knowledge of the subject."

Apes are not quadrupeds, Sofa King. If that strikes you as a semantic quibble, so be it.

[Sofa King]

Gorillas are primarily terrestrial, walk semi-erect and are quadruped. Their long arms are used in knuckle-walking to help support their weight. Youngsters and females may climb trees, but adult males can only climb sturdier trees due to their heavier weight.

I'll be kind and say that "quibble" is not exactly the right word for it.
