a thousand
The limit to the acceptability of an unreasonably high number. If you see something surpass 9000, take off your scouter and crush it in your hand while screaming 'it's over nine THOUSAAAAAAND!!'.
I saw 9001 and screamed until my voice was gone.
9000 was my limit, and I crushed it with my bare hands.
When it went over 9000, I cried and screamed at the same time.
