If White House etiquette is any indication, you should be getting a random hug soon. The Obama family was always cuddly on the campaign trail, and last month the President bestowed no fewer than nine hugs on senior male staffers at a single meeting.

The Hugger in Chief didn't start the trend. At work and at school, even on first introductions--at least among the latest inhabitants of The Real World--the hug is gaining ground on the handshake

THE FULL FRONTAL Total body contact, heart-to-heart embrace and firm squeeze. For parents, children and good friends


THE ASS-OUT HUG Nothing touches below the shoulders. Reserved for the office, bad dates and references to Vince Vaughn


THE HIP-HOP HUG A.k.a. the man hug and the hetero hug. Shake with right hand and hug with left, two slaps on the back
