Try to sound this out:
. . . "Grow-"
. . . "Growin'-"
. . . "Growin' Dyke"
Is that it? Sounds right to me! The word sounds like a butch lesbian that's getting bigger.
I see one of these trucks almost every time I stop for gas at QT and I snicker every time I see it. (I know, it's childish.) Part of me feels a little bit bad for making fun of someone's name, but . . . I'd probably make fun of my own name, too, if there were any potential.
Any other unfortunate names you can think of that you see used in businesses?
