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

A sacred dare that occurs when somebody states they will do something, saying it in a sarcastic way or not realising they said it, somebody else around them then says "man challenge" which then forces that person to do what the said or else they will receive a kick to the balls. The only way to get out of a man challenge is for the person who administers the man challenge to say "Revoke" which takes away the man challenge.
Is the person who receives the man challenge does not do the act they were challenged to do and refuses to take their kick to the balls they are stripped of their ability to give man challenges to other people because they are now viewed as a pussy and hence the name can not give "Man" Challenges.

A game where a pair or group of people record themselves watching a series of clips intended to be funny, and the challenge is to not be the one to laugh first; the one who does loses. The said record of the challenges is then posted online for entertainment consumption of the mass. Also referred to as "try-not-to-laugh" challenge, the trend has gained popularity in the end of 2000s and 2010s in general and has been widely adapted by YouTubers who and YouTube channels, such as REPLAY, which has made a series of a batch of people dueling each other over new sets of clips for each episode. In this game, various definitions of "laugh" have come up, including grinning, smiling, smirking or chuckling.
In his latest YouTube video, PewDiePie says, "Today, I am having a laugh challenge with Jacksepticeye and the one who laughs first, loses.'
