P2Plug
A plug for your butt that works like a phone. It sends messages through your butt to other butts. Used by cops and spies to talk in secret without being caught.
"My butt plug sent a message to my friend: 'The cop is coming.' We hid before he got here."
"I got a butt message from my teacher: 'You're in trouble.' I failed the test."
"My butt plug sent a message to my crush: 'Will you be my boyfriend?' He said yes."
