T-shirt created by Oceanside HS seniors draws criticism

Some students at Oceanside High School say that a T-shirt created by a group of seniors is offensive.
The T-shirt features a slew of words related to drinking and drugs. It also has derogatory phrases for the mentally challenged, and even references the n-word. 
Some students say while they can't defend the words on the shirt, they don't believe it was designed with any sort of malicious intent.
A spokesperson for Oceanside schools says the students who designed the shirts made an "unfortunate and poor choice" but added that it was not reflective of the district as a whole.
