A seemingly drunk Chrissy Teigen just used the Internet for the greater good of humanity -- introducing the world to something she calls the "vagina raspberry."
In Chrissy's instructional video she places her face over the crotch of another S.I. swimsuit hottie ... Brooklyn Decker -- and the person shooting announces, "This is the video called vagina raspberry."
And then, Chrissy buries her face in Brooklyn's crotch and blows hard ... on Brooklyn's vagina.
And now you know. Enjoy your weekend!
