A game played in a sauna in Finland. One person is chosen as Sauna Gollum, and goes under the benches. Sauna Gollum's objective is to poke the people sitting on the benches from underneath, and the first one to rise up becomes the new Sauna Gollum. Great game to be played with naked friends.
This dance was invented by Lorde. It was created when she concentrated really hard on feeling what she heard, which made her look like Gollum. When you're golluming you use your hands as claws, hunch your shoulders and back and bend your knees and arms. If you don't get this, just watch a video of her performing.
"What's Lorde doing, is she on drugs?"
"Nope, she's just golluming!"
To sit in some kind of seat while concentrating on texting/chatting on your cell phone and making various small but awkward noises. (e.g. snickering, giggling, huffing, audible but non-understandable words, etc.)
"What's Tracy doing?"
"Oh, she's golluming in her chair. Just ignore her."
