Stimulation Error 

An error that can only be summoned up by an O'Malley when using a visual drag and drop programming language, such as Alice.

When the O'Malley conjured up yet another Stimulation Error in our Intro. class the rest of the class laughed at him.

ill-error

A phrase anyone can use in order to have a legitimate sounding excuse for making a mistake at work, at home or when you return something, and you can't think of any other reason.

It also helps if your are or have been sick, thus bringing a little cred to your lame excuse. (Can be used in conjunction with it's 2nd cousin: "ill-advised".)

Woman: Wow! What were you thinking? Of course your pineapple is going to spoil if you bought it 3 weeks ago and left it on your kitchen counter. We can't give you a new one.
Man: Yeah, but I wasn't thinking properly...it's an ill-error. I didn't realize it because I've been sick and couldn't come into the store without giving everyone here my flu.
Woman: OK, go pick one out and I'll have someone ring it up at no charge.
Man: Thank You...(with a fake sneeze)
