When a perfectly masculine male or female has a sudden, short blast of femininity. The femininity can be shown through sexual/emotional thoughts, actions, speech, etc.. Usually takes place in males after masturbation.
"Omg, that girl is like so fucking hot!"

"I know! i totally wanted to fuck her until i masturbated. Then i just like, wanted to be in love with her and live happily ever after with her and make her babies..."

"Dude... you're gay..."

"No i think i just had an estrogen blast. After like five minutes i just wanted to fuck her again."
