I've been skinny my entire life too. Having lived in Asia for the first 20 years of my life, 4 months after being in the States I gained 8kg. I just ate SO much there. By the end of 4 months I could finish the entire Chinese takeout on my own. I like to cook pasta and eat 6 slices of toast with plenty on butter IN BETWEEN meals. I eat half a rack of ribs for dinner. I eat a medium bag of M&Ms in 3 days, and 3 pints of haagen dazs in a week.

This went on for 4 months and that was how I gained that much weight. So key is calorie intake >> calorie output. Be sure to gain cleaner calories though.
