I play Tetris on my phone, a lot. Like 20 times per day. My Tetris obsession started in like year 9 at school (I'm 23 now). When I'm lying in bed or just sitting around I'll subconsciously play it and visualise how the tiles fit together.
If I'm on a roll I'll imagine that I'm in some sort of Tetris championships and I commentate my game "Hows he going to get out of this one? He looks finished, Mike" "HE'S CLEARED IT! HE'S CLEARED IT! WHAT A COMEBACK!"
I get blisters on my feet a lot from work. I love peeling them back, letting the skin dry out till its quite hard and sitting on the couch with a razor blade, slicing bit by bit.
At home I'll sometimes piss whilst sitting, especially if I'm really tired. I think Neil off the inbetweeners said it is 'like a little treat' haha
I have never had to get up in the middle of the night to piss. EVER. It always perplexed me when I'd go to stay and friends places and their mum would tell me where the toilet was 'incase i needed to get up during the night'. What the hell people? Control your liquids. I can even go to the pub, have a few schooeys and go to bed without pissing.
Gross kid/teenager stuff...
If I was blocked up and had a lot of phlegm, I would hock it and spit it at the side of my bedside table, it would dry up and I'd pick it off a few days later.
I had a bit of acne when I was a teenager, used to pop my pimples then wipe the head/puss on the frame of my mirror. I'd let it build up and after a while I'd get a bit of toilet paper and wipe it all off at once, was pretty gross how much would build up on it after a couple of weeks.
