A nickname given to a person with a lot of courage compared to another person. It can often be used a compliment, as in a person who is able to achieve their goals no matter what stands in their way.
For instance:
Person A- "Hey, I hear that Abby can't achieve anything because she is too scared..."
Person B- "No dude I think you'vegot her all wrong I hear she's a right Aslan!!"
When smokingmarijuana, there's always one hit before it's cashed. instead of saying "I think it's done, but I'm not sure, you try it" just say "It's schmegged" instead.
