I grew up in the 60's & 70's so I miss several old school words.
My mother used to ask, "Where are you kids
gallivanting off to?" [traveling, roaming]
Another we'd hear is, "Who is he
in cahoots with?" [partnering in crime, in league with]
"
Far out!" [really cool, awesome]
"Don't get
keyed up about it." [anxious, too excited, restless]
"Not my
bag, man." [not my thing, not interested]
"
Dig it!" [understand it, get with it]
"
Right on!" [I agree, Yes!, Exactly!]
