That look

Just fart in their face to show them who's alpha.

i just did that in front of my cat and he gave me that look

When your pet sneezes in front of you and you crack up laughing and then they give you that look but sneeze again and you end up laughing even more

I have a pet crevecour chicken who is always sitting on my shoulder and whenever I sneeze or laugh too abruptly she gets her eye real close to my eye and just stares like she's sick of my shit and dares me to startle her like that again. XD
