Better stop or I'll drop a nickle on you!! Or later, Drop a dime on you?
One word that has stood the test of time is "Creep or Creepy", no one has found an adequate replacement for that word. I frequently hear young people say, "That guy is creepy" or "That guy is a creep".
Remember, "The girl I went out with last night was fine!!!" Or, "She's a groovy chick!"
