1) The Nervous Host
Gets drunk early waiting for people to arrive. Passes out in bed by ten.
2) The 'We Can't Stay Long' Party Hopper
She's just 'stopping in' for a glass. Makes it pretty clear she's off to a MUCH swankier soiree later. Leaves once the hot canapés have all been eaten.
3) The Chablis Snob
Fears the £4.99 bottle of Gallo. Spends the evening topping himself up with a discreetly-placed bottle of 1998 Chateau de Fieuzal he brought with him.
4) The In-Depth Smoker Chat Man
Spends most of the evening rolling cigarettes for the social smokers on the patio steps. Loves a deep conversation. Doesn't ever really come into the actual party.
5) The Empty-Handed Bastard
The 'sorry I couldn't find an offie near yours' excuse doesn't stop this person from drinking more than Henry VIII at Christmas.
6) The 'who's THAT?' girl
Shows up in a Gucci frock, over-the-knee boots and a Farrah Fawcett flick. Blows all the LBDs out of the water.
7) The Party Angel
Arrives on time, helps hand around food, makes sure the drunk lady gets a registered cab home and placates angry neighbours at 1am.
8) The Spotify Hog
Thinks his dubstep-jazz mash-ups are what the crowd really wants, even though everyone's busy shouting 'put on Mariah!'
9) The Surprise Fatboy Slim
The evening's unassuming star, who manages to shoo away Indie iPod Hog and rescue the music. Has everything from Disney to James Brown at the ready.
10) The Dancing Queen
The first to push back the sofa and get everyone dancing. She's got all the moves to the Macarena and she doesn't care who knows it.
11) The Obscure Liqueur Pusher
Thinks it's a good idea at 2am (when all the decent booze has gone) to start pouring out shots from an old bottle of 70 per cent-proof spirit the host brought back from their Greek Island holiday four years ago. Gets blamed for everyone's hangovers the next day.
12) The Second-Wave Saviour
Just when the party atmosphere is starting to sag, this person arrives late from another do, slightly pissed and wearing a skewiff pair of reindeer antlers. Gets a drinking game going then cops off with your single friend in the upstairs bathroom.
