Train Face 

An ill grimace used to deter potentially harmful and unwanted train passengers from invading your personal space while commuting on the train.

Yeah...I'm already on my way, Chief. You should see this primo trim on the train right now! I'd step to her to say what's up, except I'm still half-hammered and didn't shower yet.

...plus she's got the TRAIN FACE in full effect. I'll just perv out on yo' moms when I swing through instead. Peace.

A slutty girl that had a rat face and talks about explicit sexual stuff in trains in front of strangers.

Facebook Trail 

The "trail" someone leaves behind as they comment, like, or chat to you about as they scout/stalk your Facebook page. Sometimes, if lucky, you can see the trail navigate through different albums/time periods of your posts and pictures.

John: Hey dude like this pic!
Gary: Thanks man.
5 minutes later- John liked your comment
Gary: Hmmmmm
5 minutes later: John liked your picture
Gary: WTF! Doesn't he know he's leaving a facebook trail?
