I recently discovered that my good friend Gertrude's full name makes Gus (Gertrude Ursula S.) anyways, I think Gus is an okay nickname/name, but I think Gus belongs in my time period. You don't see many young people named Gus do you? Thanks for reading :)
It's a tad old-fashioned, but not in a bad way. The name is short and simple, and not too boyish either. It's not the greatest name out there, but it's not bad either. It makes me think about Gus Gus (or gusgus), which is a rather ambiguous association to me, as the band was cool in the 90s but has been crap ever since.
