“Roses are red, violets are blue, I have 5 fingers, the 3rd one’s for you”
Saying curse words and using the dirty finger; yes, that’s what bestfriends usually do to each other. This time why not throw them something poetic that will catch their attention, and make them feel like you are going to say something positive. This will be absolutely epic! Watch out for their reactions when you spill the last part. They might think that it will be “I’ve never met anyone as beautiful as you” or “my heart is full of love for you”, but no, it’s your third finger that’s for them!
