The clavicle compliment 

Yes always a good one to have up your sleeve. If you want to insult a womans tits to her face without her knowing, tell her she has a nice clavicle

They have to be really shit tits though or it doesn't work

Use the clavicle compliment when you really mean "those are some awful fucking empty tits"
