Goblocks

One of the considered names of Roblox from 2003 to 2005, alongside with Dynablocks.
Unlike those 2 names, it never had a actual logo, despite that there was a fan art of it.

Dude 1: hey wanna play goblocks?
Dude 2: yes, and btw It’s called Roblox, but that name was in 2003

Goblocker

A cock. A dick. A penis.

Man 1 - "Hey, you're such a Goblocker!"

Man 2 - "What the hell is a Goblocker dude? A cock. You know, coz they block sluts gobs. ZING!"
