I'll never wash my cheek
You say this when you refuse to wash a part of your face because it’s been touched by someone you like.
He kissed me, and I said, 'I’ll never wash my cheek, it’s been touched by my crush.'
She kissed me on the cheek, and I left it there like a souvenir.
He gave me a kiss and I said, 'I’ll never wash my cheek, it’s got his germs and his love.'
