To 'Simply Ham' somebody is to attatch a sticker the person without their knowledge.

The term originated in England when a girl pulled off the sticker from her 'Simply Ham' sandwich and stuck it to a girl sat behind her who then didn't realise what had happened until twnety minutes later. After that, the term quickly spread throughout northern England and is starting to hit the USA.

Guy #2: Omg, I wonder how long it will take for her to realise!
