I saw this expression in the computer game Viscera Cleanup Detail: Santa's Rampage on a time clock:
Attention: Do not put gum on or around the device. Any and all perpetrators will be bumped up for reassessment.
And in the dictionary (Macmillan), I've found only positive meanings for bump up:
to increase something
to move someone to a better position or job
But this meaning here seems to be negative.
I understand reassessment simply as assessing again. The developers are from South Africa.
