spaced out
Things that should not exist in the 21st century, #7126: commercial websites where you have to enter your card number without spaces because some moronic moron was too moronic to write one line of code to take them out or to parse the number complete with spaces.
The particular morons I'm thinking of on this occasion get extra credit for (1) providing an error message that gives no clue what they think is wrong with your card number, and (2) taking the opportunity of your having to re-enter your card details to re-check all those "spam me harder" checkboxes on the purchase form.
