siamese twinning 

When you are being cock-blocked so hard by a girls friend that she doesn't leave her side the whole entire night.

Guy: Yo, did you get with Emily last night?
Me: No man, she was siamese-twinning with Lily the whole time.

That girl is always siamese twinning with her friend, you never have the chance to make a move.

Tronning

Tronning is the act of dressing up like a robot and running through large groups of people. This leaves the people in a state of amazement and confusion. While tronning, a common thing to do is asking pedestrians to "press buttons on the control panel". The control panel is often placed on the chest or back area.

My friend went tronning through Japan last week. He rode crowded escalators and had people press his buttons.
