Plotting Definition Versus Time

I'm collecting data for a chart. y=kx The raw data is english words, and I'll plot that to show how their definitions change with time.
For now, I only have a few words ready to go.

1. Rebel.
Can be rebel forces one day, the next day "peace-seeking" world leaders recognize you as legitimate rulers.
2. Freedom-Fighter
This changes to terrorist on the time scale as well as geographical location.
3. The One.
One day he/she is heaven-sent. The years roll by and his/her name changes to "blood-sucking-ex".


Thats life.
Got any words to add?

Word definition: Junk

Junk is something you kept for years and never used then suddenly had a need for it 3 days after throwing it away.
