The angry grill (commonly referred to as the resting bitch face grill or RBF grill for short) is an after market accessory commonly placed on Jeep JK's and more recently JL and gladiator models that are custom built for Mall crawling. The purpose of this grill is to give the Jeep a more aggressive look thereby giving the owner a confidence boost equivalent to 1.5 inchs of penis growth, but in reality they usually just end up giving the Jeep the appearance of a baby manta ray.

When you think up something brilliantly righteous while baked.
