This is something you might call "european version" because Chekkazzs' Space Bwoi is sometimes called Star Bwoi (maybe by mystake). To be clear: "boy", "bway" and "bwoy" all refer to the same thing - a boy.
It seems that an important part of this move is keeping your head in one "center" spot while moving your legs to the side.

Sekkle dung in Jamaican means probably "settle down". It's the newest step created by Bermuda Kidd dancer, for sure you know him - the crazy one from RDX's music videos.
The idea of the move is similar to "calm dem down". Hands are pretty close, palms facing ground, little quick moves in front of you. Mixed with other - check the video.

As they said in one vid: "monkey lookin' somn ya?" :)
A very important thing about this move is ralaxing your body, a neat bounce at every step and adding synchronized fluid arm movements. Although depending on your preferences you can stiff the upper body a bit or make more firm arm movements. When changing direction you might try standing on your toes a little.

This move consists of two elements. First show your sneakers (heel), so raise one of your legs - bent in knee and turn a bit. Move forward while doing so. Than go back - accenting your heels so shuffle.

Jump as if you were running but without forward movement. Try to hover for a brief moment while jumping. Move your hands, lean body forward. While hovering you might touch head with your palm.

The newest step by Camron One-shot from France! Happy B-day! :)

Dance move probably based on the way Bounty Killa moves on stage, popularized thanks to Ding Dong and the 'Killa Swing' video. Hold a microphone in one hand and twist your shoulders to the sides.
Check out the mentioned video, around 26s. you can see Bounty Killa actually performind the dance.

"You are not allowed to do this!"

Crazy bounce with going down.
