Things you can't unsay
General is the topic when nobody picks, and it comes up more than any other. Anything regrettable that fits the letters counts.

I licked it first

How it works
Everyone at the table gets the same 3 to 7 letters. You have 30 seconds on Turbo tables (60 on Classic) to write a line where each word starts with the next letter. Then the lines are shown without names, everyone votes, and the winner picks the next topic. General is always one of the choices, and it's used whenever the winner doesn't pick in time.
