I will be going to my first anime convention soon..........what to expect?

Free Hug Signs.
Yaoi Paddles.
Glomping.
And over priced merch. xD
There are perks in it to, like the really nice people you can meet and the cosplay masquerade ^^

ure gunna see alot of free hug signs i mean ALOT of free hug signs

It kind of depends on the convention.
What convention are you going to?

MCM london expo may

Okay.

The good:
Masquerade
Pretty decent stalls
Some brilliant cosplay
Spending time with people out side
Some of the panels

The bad:
Free huggers/glompers
Yaoi fantards
Yaoi paddles

The general stuff:
Get used to lots of people. I think October this year for 25k + people.
Get ready to queue for things, especially cash machines and the really popular stall. And be prepared for being patient.
You'll be walking around a lot, so make sure you're in shoes that are as comfortable as possible.
The games area is pretty cool.

Meh... Expos are generally okay, just avoid the yaoi fantards and you shouldn't have a problem.

Expo = Not a convention...

Depends on what you definition of conventions means honestly? Its a losse term to say the least.

Convention : an assembly of persons met for a common purpose ;

Anyways the expo is a bit Zany by normal con standards, but its alot of fun. Just remember to pack a lunch cause food is god awfull expensive.

expect the unexpected *actually not a cardcaptor eng dub quote* really just go with an open mind and try and be vigalant against anything with yaoi in the title that isnt a tastefull manga ^.^ good luck your gonna love it

ps: I kinda get this ive only been to one con in this situation but my first con i didnt have a cosplay and i felt like crap O_o just an afterthought.

london expo, be prepared. get there early and good luck 4 ur first expo.

take note of wot every has said its all true. glompers,
free hugs,
way 2 many ppl.

mb will c u there

I'm gona take a chance and say - I was aiming to go to the same event and am not knowledged with what:

Free hug signs/gloppers
Yaoi paddles...

mean!?

Ah, the second you enter you'll know what they mean, but I shall warn you beforehand

Firstly, there is a multitude of people who charge around with signs saying "Free hugs" or "Free glomps" (glomping is basically extreme hugging, with jumping on someone generally involved, apparently people tend to do it to people who aren't expecting it, although this has never happened to me.)
The general idea is, if you see someone holding a free hug sign, they are inviting people to come and hug them. Some people find them a nuisance, but especially on your first expo it's easy to get hyped up and excited. Just don't go lobbing yourself on someone without their permission

Yaoi paddles:

Wooden oars with yaoi/yuri/seme/uke/other such things written on. Used by yaoi fangirls for spanking people with. Again, apparently this is sometimes done without permission, but I've not seen it. (Apart from my friend who kept spanking me with hers, but what're friends for, eh? >___> )

Thanks for the heads up, will keep that in mind.
