The O'reilly

When you think a girls tits are so amazing you can't possibly do anything but fondle them and you want to be inconspicuous, you look away and reach across her chest and gently push your elbow into her tit in multiple places more or less searching for the nipple all along thinking she has no idea what you are doing because you are so drunk.

That girls tits were so fuckin unbelievable, I gave her the O'reilly! She never knew what hit her.
