1. Having tattoos. There are nice tats but they eventually become ugly. In general 90% of tats are horrible. 2. Smoking. So 20th century. Disgusting habit. Shows lack of self control. 3. Being fat. This requires no explanation. 4. Getting excessively drunk in public. You are an embarrassment if you do this. 5. Wearing sports jerseys anywhere but at a stadium or arena. If 3 or more apply to you, you are a lowlife guttersnipe.
