Put one right over the plate, Eddy.
Lipshake: Greeting a friend, a co-worker, an acquaintance, an acquaintance's mother, father, sister, brother, maiden aunt, great grandfather, former high school teacher, or plumber with a kiss on the cheek.
Or two, one on each side.
And we do mean the high cheeks.
Where practiced, this is more common among women. Men, being more manly, do a cheek bump, or just hug briefly. Sometimes they only shake hands. If they are oddly stand-offish for some obscure cultural reason which you will never learn the timing of.
Like everything, it takes you a while to catch on to what's happening. When in doubt, grin like an idiot and chuckle nervously.
