You're the man now dog(ytmnd.com) has becom a famous website. PTKFGS, has become a fad on ytmnd.com as to what the website might have been called.
PTKFGS originated as a fad on the cult website ytmmd.com or "You're the man now dog dot com" which features webpages usually dipicting arguably humerous background image and background music. PTKFGS was started when a user created a page depciting an alternate universe of what ytmnd.com might have been had the website creator chosen the former quote rather than the ytmnd latter. As a result users took previous existing pop culture fads and slightly altered the imagery to create a distinct "alternate dimensional" parallel.
The fad lasted for sometime with many humerous spawnings.
It is a line from Finding Forester said by Sean Connery a few moments before the now classic internet catchphrase "You're the man now dog!"
Punch the keys for God's sake! (ptkfgs)
*punch punch punch*
You're the man now dog!
