^^^^înteresting,i have found this lyrics maybe he refers to How to rob when he talks about his weight :
the song is watch those (last verse):
Can't no comp come at me, this battle the Bronx'll back me
Got the nicest niggaz alive talkin bout, "Papi's nasty"
Cocky crafty like Rocky sassy Puerto Rock Apache
Posse not even the cops could catch me
I'm too fast - four-hundred pounds, but I move ass
Soon as you spoke, I already smoked you with two jabs
My game is tight - you wanna play, just name your price
Fame to ice, your brains your life, the game is sheist
and I'm the trifest on the field
Even in school I was nominated the most likeliest to kill
This bastard steal, a full clip and a extra
and I'ma blast ya til your whole click respeta
Leave you muerta, it ain't me it's the metra
'tate quieta, the bitch got a bad temper
Don't surrender - you ain't got a chance
You be lucky to leave here half-dead, in an am-bu-lance
So take a chance, but expect the worst
Put my foot so far up your ass
the sweat on my knee'll quench your thirst
