Quick Translation Help
 

I'm trying to learn Japanese, but I can't make head or tales out of this photo caption:

ちょーかっこつけ

If anyone could help me out, it would be much appreciated.

It means "Super show-off" or "Trying to look cool"

ちょー : Super, very, clearly

かっこ : Appearance

つけ : attaching, adding on...

in this case adding on something to his appearance so "adding something fake"

lol This is something your dictionary won't help you understand. It's all colloquial.

ちょー means 'very', 'extreme(ly)', 'really', etc.

かっこつけ means someone who likes to look cooler than he actually is or the act of trying to look cool.

So, ちょーかっこつけ means "(Someone is) trying really hard to look cool."

(Only the context will tell who that someone can be. )

EDIT: MMM beat me to it.

This time I beat you, Nagoyankee!
