Nickname for Detroit Lions wide reciever Calvin Johnson. Has this nickname due to the fact he has huge hands that resemble a Decepticon.
Guy 1: What's the point of watching the Lions, you know they're gonna suck as usual.

Guy 2: Don't be so hasty on your decision, Megatron has been bringing on the TD's recently. They might actually make the playoffs this season.

A penis that exhibits the "grower" characteristic of significantly expanding and lengthening upon erection as opposed to the "shower" characteristic where it is already near maximum size at rest and does not get much bigger upon erection.
Hey, baby. How you doing? Don't be fooled by the Decepticon in my pants. My Megatron is full of destructive force capable of making you/your Starscream.
