At first we had Veronica responding to Ryan's comment with "As if!" However, it seems a lot of people strongly associate that particular valley girl speak with the mid-nineties due to the movie Clueless, so we thought it'd be better to go with the more '80s "I'm so sure!"
"As if" does relate more to the 90's. While many catch phrases and slang are more generational than culture driven I can see how it may be tough to keep that "correct".
It's frustrating how hard it can be to find out what era certain slang words and phrases were actually prominent during. At one point, we realized that having Trish say "
Whatever, Dean," back in Issue 1 sounded a bit more nineties than we'd intended. I think I remember Adam reading something about how it was used in that way in the 80s once on
The Golden Girls or something, but it didn't become a real bimbo staple in that "What-EVERRR" sort of way until the nineties.
Looking this stuff up a little bit just now, I learned that there's a thing called "sexy baby voice." Gah.
