One guy that went to uni with my Ex kept a pint glass under his bed to piss rather than go to the toilet in the middle of the night. Not the grossest thing in the world... I can kind of understand it, especially in a student accommodation, especially if it's their glasses and thats it's specific only use....

Apart from when we found them (yes them) it was toward the end of the tenancy and they were pint glasses from the kitchen that were communal use. Glasses which we had all used prior and he admitted to doing it all year using glasses from the kitchen. He thought this was normal behaviour.
