Surprise motherf**ker

so cute, little cub acts so big

I used to do that. I used to go around and spook my dad and then I would climb on act as if I conquered a giant, he used to play along. Sweet Times.

lol my neighbor's daughter was playing with a basketball earlier today, and while I was outside having a stogie out of the corner of my eye I see him sneak around the side of his house as she was putting the ball away in the garage and he goes "BWAHHH" really loud and she screamed... I quietly chuckled.

Look, mama's ears are turned back to listen to the baby. She's pretending to be scared to encourage her little one like lions do

Cats do this the world over.
Big cats often creep up and scare each other for a laugh.
There's a guy on YouTube that hangs with loads of them, and devotes a whole video to it.
