Is a feeling of sexual pleasure that occurs when a O.J. Mayo fan sees him do an amazing dunk or jumper. This feeling is most often felt by most grizzlies fans. This feeling will make you want to get Mayonnaises out of your Fridge and explode it all over your 40 inch plasma t.v (if you know what I mean)
Harold:"Wow O.J Mayo's windmill dunk last night was so sexy!!!"

Bill: "I know I almost had a major Mayogasm."

Harold: "Fuck you destroyed your 40 incher again...?"

Bill: "yes....damn Mayogasm's"
