When a guy introduces the girl he's been seeing (i.e. sleeping with) as his "friend" and not his girlfriend.
Chip has been seeing Sarah for three months. They have been dating and spending nights at each others places for a month.
Chip: This is my friend Sarah.
Sarah: Did you just introdouche me as a friend?!
Chip: This is my friend Sarah.
Sarah: Did you just introdouche me as a friend?!
