Even if you weren’t a child of the 80’s (apparently you missed out) and you aren’t familiar with early Beastie Boys albums you can still be rad and say “rad”. No, not the BMX movie Rad from 1986 starring uncle Jessie’s girlfriend on the original Full House. But yes, that was rad too, especially the part where they do a choreographed bike dance at prom to the song “Send Me an Angel” by Real Life. But we’re talking about the 80’s teen slang meaning “sense of extraordinary wonder.” That ‘rad’ is timeless, just like this shirt.
