a couple
A couple is like a group of seven or eight people who all think they're the main event.
My mom said, 'A couple of us are going to the store,' and I showed up with five cousins.
The teacher said, 'A couple of you need to clean the board,' and 10 people stood up.
He texted me, 'I'm bringing a couple of friends to the party,' and showed up with my whole family.
