There is a pipebomb in your mailbox

Commonly used on the app Discord. Can be used as a response for literally anything. Usually as a form of a GIF, so there would be a GIF of someone dancing with text saying "There's a pipebomb in your mail box."

Larry: "yo my pet rock died today :("

Bob: "There is a pipebomb in your mailbox".

There's a Pipebomb in your Mailbox

It means that 2 video game characters are dancing with a text box "There's a pipebomb in your mailbox" its also means that there is LITERALLY a pipebomb in your mailbox. You could use it for trolling someone like on discord, tiktok etc. Yeah, don't fall for someone who posted 2 video game characters dancing on you like they're basically taunting you.

Me: "damn.. i actually wondered if something bad happens while i check the mail."

"There's a Pipebomb in your Mailbox"

Me: "OH SHI-"

Pipebomb exploded.
