cowlster 

A prolific creator of Minecraft parodies and food reviews. Often he is English but people don't hold it against him (much). His voice is notorious for bieng imitateable. And his Minecraft skills though advanced are brought down by his idle personality.

It's cowlster!

A person who emitts a great aura of coolness.

Sometimes "funking" may be used to emphasise the coolness.
