Similar to I’m shook, I’m dead, I literally can’t even, or ROTFL,ย  “I am screaming” is a way of indicating that something is so striking, that it’s scream-worthy. It is a way of showing extreme reactions including surprise, amazement, and amusement. The phrase can also be used more dryly and sarcastically like in the damn bro you got the whole squad laughing meme.
