Marble Up 

To gain weight through extra fat "marbling". Term derived from cattle industry practice of fattening animals prior processing into food. This fat, streaked through the meat, provides extra flavor and richness.

Observing your friend downing a large bowl of ice cream, you say: "Marble up dude!".

Exclaiming to your ultra-fit skinny buddy: "You need to marble up!".

Marbled Up

When something sounds very unclear/unrecognizable to the ear. Something about whatever you are hearing just isn't quite right!

DD: I wouldn't recommend listening to your drums and your ipod through the same speaker, you should split them up into different channels, if not, it will sound real "Marbled Up"!

Longo:Those chicks want us to pick them up tonight but they live 50 minutes away:
GD: F,, that, that plan sounds "Marbled Up"!
