The Marc Challenge 

When you eat a girl out for more than twenty minutes and within 24hrs you text her to let her know you're not interested in seeing her again or dating, a power play used by men who want to treat women well but can't commit until they find someone they really like

Man, I shouldn't have done The Marc Challenge but I kept going out with her and finally had to end things after I ate her out for twenty five minutes
