The other day my 15-year-old daughter gave me a tutorial on expressions that teen-age girls use. (My guess is that boys don't use these as much.) Here goes:
Awky: adj, awkward, especially referring to a social situation.
Cool: adj, an all-purpose word to be used to express approval of virtually anything or anybody.
Legit: adj, used to express even stronger approval than the somewhat mild "cool."
Sketchy: adj, doubtful or weird; a claim which is somewhat dubious; can also be used to express disapproval of a person about whom you have misgivings.
TY: Short for "thank you"; to be used only when wanting to be purposely obnoxious.
GTFO: An internet acronym (short for "get the fuck out") adapted by teen girls for spoken use; must always be said with an implied exclamation point at the end.
STFU: Another internet acronym ("shut the fuck up") to be spoken with the same breathless delivery.
LOL: Yet another acronym, but to be used in spoken language only in an ironic way.
If you're the type who enjoys watching your teenage daughter squirm, use these words in front of her friends.
It'll be very awky for her, guaranteed.
