stu 

To avoid that which tempts you (be it due to laziness, possession of inconvenient moral values, lack of quids....)

To declare temptation but not indulge is to commit a STUism.

Examples of STUisms:
"I'm tempted, although I'm rapidly becoming very broke, so I'll give it a miss..."
"I want to stick things in you but I'm married so I can't"
"I want a brew and a mint timtam but I can't be arsed to get off the sofa"

A cheesy guy who has a striking resemblance to Keanu Reeves. A guy who thinks he's very cool. A poser.
