Valérie in Tout sur moi says good-bye to her two closest friends Macha and Éric:
Bon ben… à tantôt, gang.
“OK, so… bye for now, guys.”
She called her friends gang. It sounds like the English word.
[Quote from Tout sur moi, “Coma,” season 5, episode 10, Radio-Canada, Montreal, 16 November 2011.]
Why does she drop the definite article here?
Both ways are possible. By the way, gang is feminine — la gang.
