Define One Way Ticket To Hell Meaning

One Way Ticket To Hell
What you say when someone (a half-friend, a leech, etc) is bothering you and keeps asking you to buy him something while you are in line at the fast food place.

Guy (Walking up to you in line): Yo, buy me something!
You: I'll buy you something alright...a ONE WAY TICKET TO HELL
Guy: I sincerely apologize. I will now serve my community and donate blood.
