what does M&G stand for on twitter!!?

[mina]

ok this may sound stupid but seriously what does M&G stand for on twitter. everybody is tweeting it here is an example: Justin: "Now that I'm 18, I'm getting more mature." Says the 18 year old who wore Heelys to his M&G<----- this is what i'm talking about!?? or this: Justin looks SO tired in his recent M&G<---- pics.

i Hope you will take some of your precious time to answer this question! THX
