His was a true biceps.December 13, 2010
Before you judge my grammer (was vs. were), think about the following. The singular of biceps is actually biceps.
Confused? It gets worse. The plural form is not biceps. It is bicipites.
You could try using bicipites at the gym (i.e. “Dude, check out my bicipites!”), but I wouldn’t recommend it.
