A wedding where something is obviously very wrong, or out of place
Where everyone knows about it but no one will talk about it
In most cases the bride or groom is secretly gay
A brand of cigarettes in France. All the cigs are pink and have vanilla flavoring (a.k.a. they are amazing) They come in a black box with a pink elephant facing backwards on it and "Pink Elephant" written in pink.
Joe: Hey can i have a cigarette please?

Joe: OH SHIT these cigarettes are pink!!!!
