Attempt to inflate ones own image by claiming you've slept with a woman you really just masturbated to. Typical female subject way out of your league (see: Reputation Urination).

Frequent acts of Reputation Masturbation may result in fapnapping. Typical offender lives vicariously through dude bro friends who actually get laid.
Dude bro: you see that hottie Katie on the second floor yet?

Offender: hell yea bro, I banged her last weekend
Dude bro: you mean you banged your hand and fapnapped last weekend. Classic case of reputation masturbation.
