Anything to take my mind off the fact that I'm working late... again

Here is a list, in no particular order, of words I overuse, some when I write, and some when I speak (can you guess which are which?)

- seriously
- cool
- brilliant
- fab
- actually
- meng (okay, not a real word)
- hello
- timeline
- process
- issue
- encode
- tracker
- lekker (Dutch, but still)
- totally
- doei (again with the Dutch!)

And, to balance things out, here's a list of words I should really use more.

- gobshite
- blimp
- squishy
- muppetry
- pernicious
- no

What words do you over/underuse?
