A common phrase
or figure of speech
where you forget to leave a way out for yourself
Happens all the time to novice painters. If you're painting the floor, sometimes a shortsighted person will paint the doorways first. Usually they don't catch on until they have managed to cut off every exit with fresh wet paint.
If you are caught in this:
1. Smack yourself upside the head.
2. Look for an alternative means of escape. Can you climb over a table/ counter? Out a window?
3. Walk across the wet paint. Not much choice, man. Get some paper towels for your shoes, and get more paint.
4. Wait. Hopefully this stuff might dry soon.
