PSF

When someone's face clearly shows signs of having had work done, pulled back skin, large lips, funny smile, etc. This is PSF or Plastic Surgery Face

1: WOW - her smile was permanently attached to her face.

2: No kidding, but it IS permanent; that is a bad case of PSF

PSF

"Pure Sober Fun". The type of fun and partying that occurs with your parents or goody-goody friends. It is likely that there will be no alcohol or drugs involved, only board games. The 'fun' is used sarcastically because in reality, there is no fun in being purely sober.

We couldn't drink last night because Monica was there. It was PSF.

PSF

Plastic Surgery Face. When too many plastic surgeries have caused someone's face looks like a half melted doll's head.

If you were the hot chick in an 80's hair band video, chances are you now have a serious case of PSF.
