OONSK 

A meme started on the Halo: Reach forums. When you zoom in on one of the arms of Kat from the Halo Reach logo, you see the letters "UNSC" with bolts making up the eyes, some metal that makes up the mouth, and after cut out, arms and legs.

Example: "We love OONSK!" pictures.

see "UNSC."

oomska

A word which collects all things that are mucky, dirty and of the ground. Especially things that are wet, brown and sticky.

As In Monty in 'Withnail & I':
'You mean you've been up here in all this beastly mud and oomska without wellingtons? This afternoon I'll take you both into Penrith and get you fitted with some good quality rubber boots.'
