A word used to either be said when someone has nothing else to say or to speak when you are literally showing no interest on a person talking to you in an obvious way.
Example 1:
"So science can be very helpful in many different ways such as observing how nature works,learning how your surroundings behave,learn how everything functions blah,blah,blah and stuff..."
Example 2:
Person 1:
-"HOW MANY TIMES HAVE I TOLD YOU T-"
Person 2:
-"blah blah blah,this thing again?Yeah yeah i get it."
A blah is another name for rolled up Cannabis. It is made from the plant Cannabis Sativa. It's intended purpose is for use as a psychoactive (mind-altering) drug.
The main psychoactive ingredient in a blah is THC (delta-9-tetrahydrocannabinol), but more than 400 other chemicals also are in the plant.
Immediate physical effects of a blah include a faster heartbeat and pulse rate, bloodshot eyes, and a dry mouth and throat.
A blah is normally made by taking a cigarette and replacing out the tobacco with cannabis. A blah can also be made by using rolling paper and a filter.
It is common practice to smoke a blah in a group and follows the concept of puff-and-pass.
A blah is a non-descript, boring, often stupid person that no one pays much attention to. Could be someone sitting right next to you at a restaurant, a bus stop, work, school, etc.
Often thought to be urban legends, but that's just because no one notices them.
1. Having a conversation with a blah like like talking to a rock. Except that the rock is actually kinda cool.
2. Some day the blahs are going to revolt, but nobody will care.
3. Have you ever seen a picture of a blah? Neither have I.
