Definition #1 for "no fap september no fap months"
No Fap September, and other ?no fap? months, are challenges in which the participants must abstain from masturbation (known as ?fapping?) for an entire month. While participants may not pleasure themselves during the course of the month, they can engage in sexual intercourse with another person. The challenge bears many similarities to the 7-day No Fap Challenge, in which male Redditors attempt to cease ejaculation for seven days in order to raise testosterone levels.
