Duicide 

Duicide, or duo suicide, is when you commit suicide with a family member, friend or even a stranger.

Credits to my friend, {insert name here: } for..well...I don't know why really. But credits to him.

Person 1: "I wanna die."

Person 2: "Same..wanna duicide?"

Person 1: "Sure, I'll get the rope."
