Breezer is an alcoholic drink, much adored by people often still under the drinking age. It is a mix of Bacardi Rum with lemon or another
fruit juice.
In some chat channels, where the majority of visitors belongs to the breezer-addicts, it is 'cool' to talk
BrEeZaH. It is a bit comparable to 1337-sp33k and can be identified by the use of capitals and other characters in places where they don't belong, and replacing characters with same sounding ones.
Beeing a BrEeZaH-person is often considered being lame, by people who have more than 1 brain cell.
I don't know in what way this BrEeZaH-thing is knwon world wide, but in the Netherlands it gets pretty annoying.
