Spongebob exposes Riot's agenda

Milk: could stand for how RIOT milks you for your money. With the recent complaints about the God-king icons being trapped behind a 5000 RP pay wall, the recent transition from IP to BE, emotes to spam at enemy players so you look good.

This could also stand for the large breasted female champions in the game. Implying MILK or in this case breasts are essential to healthy gameplay

"You cant milk those"- alistar

Eggs: first thing that comes to mind? Anivia? NO, its that the egg came before the chicken. In this case pro-play comes before casual players

Cheese: pretty self explanatory. Lucian lvl 2 cheese, akali lvl 6 cheese, big mac with no cheese. You get the picture, Riot promotes cheese. Possible secret sponsorship from kraft singles?
