International Come up With a Day Day or (ICUWADD) is that day where you feel "wow my job is retarded" and decide to make up a holiday to miss work. Of course because your job always sucks this makes any day that isnt a real holiday (ICUWADD) and allows you to miss every day of work while still claiming a pay check.
Man: "My job sucks"
Joe: "Thats ok dude, its International Come Up With a Day Day"
Man: "I always forget that everyday is ICUWADD, thanks Joe!"
