Where college girls get tattooed during their freshman year so that everybody can tell them apart and determine what clique they are in, because they all wear the same jean miniskirt and school hoodie as every other girl on campus.
Here's what each girl usually winds up getting:
Sorority girl = butterfly or dragonfly on one ankle, sorority letters on other.
Lesbian = poem, black cat, or Siamese cat
Party girl = sign of the zodiac (not necessarily her own)
Athlete = Kanji symbol that the coach talks all the girls into getting, because it's a word of inspiration such as "strength". It almost always means something entirely different than what the coach convinces them it means at the time they get it.
So many college girls get tattoos on their ankles (even though the trend was supposed to have waned after the Friends era) one begins to wonder if it is some sort of school policy.
