I don't get the rekt part either. I think they think that a dog would consider it a deep insult to be told that he was incapable of taking down very large prey. I've never seen a dog that took any interest in size before deciding on the probable outcome of a fight. They care more about posture and noise level when deciding to fight or not. But then this dog is texting... so perhaps there is room to believe he's smart enough to understand the insult!
