your friend. a "couple", like in relationship terms, is two people. or, the way i figured out the distinction between a couple and a few is this, and ill warn you now, its crazy-stupid. you see, "a couple" has three sylables, and i memorized that three is not a couple, but "a few" has two sylables, and two is not a few, so...yeahh. like i said...crazy-stupid.
It depends on what you are talking about. If you mean people, it means 2, like "David and Elaine are a couple." If you are talking about peanuts, glasses of beer, or the equivalent, it means a few, as in "let's have a couple of peanuts."
Your friend is saying Jessica and Jerry are a couple!
That is correct...
You are saying "Can i have a couple french fries"
which you would be right two...
But out of both of you, i would say your friend is more right than you are
But you both are correct,
If you want to get technical, 'couple' is just two. Example- "May and Brandon are a couple." They're called a couple because there's two of them in the relationship.
