2.
One who smokes marijuana regularly and is constantly in a dazed state of non-remembrance and forgetfulness. Some consider shot ass to be a synonym for the word stoner, but this is not the case. All shot asses are indeed stoner's, but contrary to popular belief, all stoner's are not shot asses. A stoner is defined as one who smokes a ton of weed but is not necessarily always under the influence of marijuana. A shot ass on the other hand never allows himself to fully reach a state of sobriety and will constantly be seen puffing on joints or stealthily smoking in the school bathroom to keep their buzz going strong.
