Sir Hammerlock doesn't like the name given to Bullymongs, and wants you to help him in researching them to think of a new one. For now, head to Three Horns - Divide, and start looking for and smashing the bone piles, which are the green glowing ice chunks. There is an optional objective of killing 15 Bullymongs for this mission, which shouldn't be too much trouble if you search around for them.
Once you have smashed 5 bone piles, Hammerlock will chime in and start going through some name changes. The first one is Primal Beast, and your objective is to kill one with a Grenade; your best bet for this is to find a Monglet, since those are the weakest. When you do that, the next name change will be to Ferovore; your objective now is to shoot three projectiles thrown by the Bullymongs. Your best bet for this is to find some Slingers, sit back and shoot the rocks they throw.
Adult Bullymongs can throw projectiles, too, but they tend to favor getting up in your face, so if you manage to find a Slinger, keep it alive until you finish this part of the mission. The last name change is to Bonerfarts, and all you have to do now is kill 5 of them. Once you're done with that, head back to Hammerlock to finish the mission.
