MacTavish
MacTavish is when you take a huge risk and have unprotected sex, hoping it doesn't blow up in your face.
I told my friend he was being a MacTavish and now he's got a yeast infection.
My sister said my brother MacTavished her and now he's got a rash.
My brother texted me: 'Just MacTavished my ex, and I'm paying for it.'
