I've seen the word 'frob' used several times in discussions about System Shock 2, such as at:

"Does the data just sit in your inventory modifying stats or do you have to frob it or what?"

What does 'frob' mean, please? From the context, it seems to mean use or extract somehow, but I'm not sure.

Should be called RCtU then, no? 

Just remember to wash your hands after frobnicating.
