Mental boom is when a series of unfortunate events happen and another unlucky scenario presents itself causing you to lose your shit. This may happen by talking to that ONE fucker or any other triggering thing. This causes you to lose your shit for the rest of your day and tilts the fuck out of you and you feel like committing sudoku.

Variations of this include:
mental go boom
mental go sky
holy fuck I'm just mental boom
