"Sound" sending App???

When I got my first iPhone there was an App my wife and I used that was kinda funny and I'm trying to find it but can't think of the name. If both people had it installed, one of them could send a sound to the other one and it would play automatically. It had a ton of funny sounds to send that would really ruin the other ones moment if it was sent at the right time - hahah...

Anyone know what this App is called - I cannot find it

 

Yes!! Hahaha thank you!!
