Ya know, normally if someone said to me "team liquid goliathus' I'd assume they were suffering from some kind aphasia, like in that episode of Deep Space Nine. So, to keep the theme, I'd probably respond with a smile "glass lunch judge; a bin, to let it", and we'd all laugh.
But in this case, it means a new e-sports-themed mouse mat from the makers of more or less fine peripherals at Razer.
The Team Liquid Goliathus e-sports edition mouse mat is your typical Goliathus (I would kill to work in the department that came up with these names), with a rubber base and a slick cloth weave, but it's also in the cool colours of Team Liquid. It was their exclusive mat, but Razer's releasing it to one and all, for the handy price of $29.95.
