Roid Rage is a Chicharrón Amigo ability: once he drops below 70 percent health, he attacks faster and deals double damage. It makes the rooster more dangerous the more he gets hurt.
When Chicharrón takes enough damage, he goes into a rage, speeding up his attacks and doubling his damage. You do not trigger it; it just happens mid-fight.
It helps him carry long firefights where he takes chip damage. Keep an eye on him though, since a raging rooster at low health can still go down.
