Here's some Scandinavian input on the name Lesnar, and all I can come up with Is this.
"Le" means "Laugh" In Norwegian and "Snar" means "Quick" in Swedish.
Brock LaughQuick.. doesnt quite have the same ring to It.
Or you could add Lesn(ø)r instead of the A and It would be "Le Snow"
Well, we knew he was a bastard.
