Smiley Jacker 

One who observes the usage of cool smileys by their friends, and finds it necessary to duplicate said smiley in many different situations(however unfitting or inappropriate the smiley may be in that instance).

Craig: Hey Diana, whats going on!? I'm soo happy today! xD
Diana: Not much, Not much just about to go to work. Good for you pal.

Two Days Later:

Diana: Hey Cindy XD I think I might have an alcohol problem, help me?
Cindy: Omg Diana, that's one of Craig's signature smiley faces! Jesus stop being such a "Smiley Jacker"
