Get the Toilet bomb mug.
when you go to the toilet only to discover someone, or perhaps yourself from earlier, has left a rotting pile of shit and/or a bowl full of piss that has been sitting in the toilet unflushed.

It is especially bad if you have to lift the lid of the toilet first, then the smell of the old shit and piss explodes in your face. Much like a bomb.

Holy fuck look at that turd! It smells like someone just took a shit in my left nostril. I can't believe I just got fucking toilet bombed.
