One of my son’s friends was telling about another kid their age who kept talking about the importance of having one or more girlfriends. Supposedly the friend’s reply was “dude, we’re 11 years old.”

Back in the day, or rather night, once one of my friends said “Dude”, we couldn’t stop. I’ve had entire conversations like that:
“Dude?” (What’s goin’ on?)
“Dude!” (We don’t need anything goin’ on, it’s just us!)
“Duuuude…” (That is so wise)
“Dudes.” (Chillin’ wi’ m’ dudes is all I need)
…
“Dude?” (I’m getting hungry/thirsty/bored)
“Dude…” (Time for a 7-11/Burger Chef/Taco Truck run)
“Duuuudes!!!” (I’m lettin’ out the clutch, hang on!)
And they say English is a hard language to learn!
Dude.
