I looked up the definition of lunch.
1. Food with no chance of ass.
2. Food with no need for a penis.
3. A time when a desperate man has no chance of success and has taken the time the girl has given him for possible grabbing and reduced his chance to 0.
Alternatives for lunch.
1. Waste of time
2. Waste of money
3. A time a man is an embarrassment to his gender.
4. Self cock block
Guy: "Hey I got lunch with that Amazon girl"
Friend: "Ha, ha. Self cock block. Pitiful."
