When I was a teen, my best friend and I name out guitars as a goof. I have long forgotton what I called it.
My kids named some of my guitars. I have an LP with a nice flame top that my son calls "Tiger" because they kinda look like tiger strips. My PRS CE24 has a similar looking top, so that one has been dubbed "Tiger 2.0". Other than that, it's "my strat, my black LP, my tele", etc. Boring for sure! :)
