A term used when backing out of work last minute (even if you promised to you'd come in today) with no explanation (not even a lame one like "I'm sick").
1. "Hey, where's Keith today?"
"Oh, Keith pulled an Andy today. He's not coming in."
"Keith pulled an Andy? Is that what you're telling me?"
2. "Hey guys, I know I said I was definitely working tomorrow, but I'm thinking about pulling an Andy. Maybe I'll be there, maybe I won't"
