Every time I see a foot without a sock on it, I get the urge to take my finger and run it along the foot, so the person squirms. Every. Single. Time.

While exiting a curve I have this strong urge to accelerate so hard that the tyres squeal so much that it make people run for their lives!

Recently, every time I find myself somewhere high up, such as a building or a bridge, particularly one specific bridge near my house, I have the overwhelming urge to jump.

The only thing that stops me is the fact that I would get dirty if I jumped into the murky water below. If I could know I would land on a clean surface, I would do it.

I sometimes have to deal with colleagues who are such spiteful twats that I want to literally beat them to death with my blunt fists.

Whenever I am walking over a bridge, or beside a river I have a strong urge to toss valuable items into it, like my mobile phone or laptop.

I have a very strong urge to chew on glass. When I drink from a beer bottle or a drinking glass, I often imagine biting the top off the bottle or taking a bite out of the side of the glass.

I have frequent urges to throw/burn all my clothes

I get the urge to shove everything I see down my shirt, I do not know why, but I like it… Also I love to bite people. And animals… It makes me feel like a velociraptor. rawr.

When I’m at a train station I want to jump onto the track just as a train rolls in so that I can outrun it as everyone looks on in horror. Just as I escape it by a few inches, everyone would cheer and there’d be an article in the paper about me that I could point out to strangers.

Whenever I’m walking down a set of stairs I want to trip over and roll down them hopefully breaking one of my arms.
