"In a pig's eye!"
Heck, Kirk once joked about dipping little girl's ponytails in inkwells.
Seriously, yes, of course, realistically, people in the far future are going to speak some exotic future dialect that bears little resemblance to modern-day English, but, in the real world, the show is being produced for modern-day audiences so Star Trek dialogue has always employed contemporary language, the only nuance being just how slangy or colloquial you choose to go, which can be a judgment call.
TOS, on tv and in the movies, used fairly colloquial dialogue: "You've earned your paycheck for the week, Scotty!" "Hell of a time to ask." "Let's get the hell out of here." Etc.
TNG leaned toward slightly more formal speech in an effort to be "timeless," but let's be honest, Star Trek dialogue is never going to be realistically "futuristic," for obvious reasons.
