raptor grass 

Long, ill-cared for grass where a person finds themselves at greater risk of being picked off by prehistoric predators. Although dinosaurs are technically extinct, it's a confirmed fact in nature that tall grass is more likely to conceal Cretaceous killers than lawn that is mowed once a month.

#1: "Dude, stay out of that raptor grass, you're going to get bit by a snake." #2: "Holy shit when was the last time you cut the grass? It looks like the Land Before Time out here."

Raptor grass 

Long grass, must be long stem and very green, tall enough to hide a pack of hunting velociraptors.

Come on, keep moving - we’ll be safe just as soon as we can traverse this raptor grass.
