This is what you say when you get up in the morning and get ready for your day and you look in the mirror and you are like "Damn, i look good today".
This reaction can be a result of many things. Usually you just have on a outfit that you really like and you feel awake, alive and confident. It's a great feeling.
Today i got up, took a shower and got dressed in a new gray turtle neck and a pair of new khaki's i put on my hat brushed my teeth and walked by the mirror and i just had to say "Damn, i look good today".
Everyone should have one day a week where this happens because it feels great. Unfortunatley it never happens that often so enjoy it when it does.
