Gonna start this by saying this literally happened within the last hour. I'm a uni student, currently living with my girlfriend and four other housemates.
I, as do many people, like listening to music when I shower, so my girlfriend got me a waterproof Bluetooth speaker, with a suction cup to attach it to the shower wall.
I used it happily for a couple days, but then they needed charging. Here's where the fuck up comes - I am not a mature man.
I started playing with the suction cup, sticking it to all sorts of objects - my palm, the wall, unfortunately culminating in my forehead.
What do you fucking know, the bastard thing won't come off.
I ended up with it on my forehead for around three minutes before my gf managed to get her nails under it, and I've never seen her look so horrified.
I am now the proud owner of a 5cm long, 2cm high bruise in the centre of my forehead, and I have a meeting with my personal tutor about my dissertation tomorrow. Whoop de fucking doo.
TL:DR - not a mature man, stuck a suction cup to my forehead, massive bruise ensued, important meeting tomorrow.
I'll post a picture in the comments.
EDIT: For those asking,[here](http://imgur.com/QgDZtcH) is a picture of me with the speaker still on my forehead
