When a girl casually mentions her boyfriend in a conversation with a guy to keep things from getting too hot.
'He’s cute.' 'I have a boyfriend.' 'Oh, really?' 'Yeah, and he’s not here.'
'You’re hot.' 'I know, but I have a boyfriend.' 'Does he know?' 'No, and I don’t want him to.'
'You’re getting flirty.' 'I know, but I have a boyfriend.' 'Is he here?' 'No, and I’m glad.'
