Jersey Shore only aired 10 episodes this winter, but that was enough to lure in millions of fans, make celebrities of the cast and introduce plenty of new vocabulary words, slang terminology and acronyms into the pop culture lexicon.

Case in point: The lovely Katy Perry was seen headed from the gym to Fred Segal's in W. Hollywood over the weekend wearing a shirt proclaiming simply GTL.

GTL, for those unfamiliar with Jersey Shore quotes, stands for Gym, Tan, Laundry. As in the daily routine of some of the Garden State guidos we grew to love.

While Vinny Guadagnino said that he prefers BPB (basketball, pool, beach), he was sadly outnumbered among the male cast members, and the term stuck.

Here's Katy giving props to DJ Pauly D and The Situation:

GTL: Katy Perry knocked off the first part, but somehow we don't imagine she went tanning after this photo was taken. Laundry? Maybe. Stay tuned for more updates.
