what's you're favorite dirty move?....

there are fouls in everyfight. it's not the ones that the ref calls that are interesting. it's the ones he doesn't call (cuz the fighter who initiated the foul hid it so well)). every fighter fouls. boxing is indeed a 'controlled' war. even cutsey footsey fighters like mayweather and jones foul. don't believe me? watch mayweather bump a guy with his shoulder as his man rests his head on his body then swing at his temple. that's a no,no. or watch jones hold and spin a guy then unleash a hook to the body or an uppercut. they of course never get called on them as they hide it very well. whether it's hitting the leg/hip opposite side of the ref, stepping on the lead foot of the opponent, hooking tight so it convenietly hits the elbow if you miss, etc. things like intentional headbutts, hitting the groin are quite obvious and signs of frustration. i want to know which ones that are used to gain an edge are you favorite...and what you have tried out? personally the spin move is great...you clinch then fake like you're comming out to engage then you spin him (slightly..too much and the ref callas you out on it) and hit before he ever gets his bearings and plant.
