look up any word, like donkey punch:
 
1.
Clothing or accessories for men that look very cool and fashionable when worn in Asia but would otherwise look completely stupid or peg you as being gay when worn outside of Asia.

While in Asia:
"That man-bag is totally gaysia." Meaning, "That man-bag is totally cool!"

While not in Asia:
"That man-bag is totally gaysia."
Meaning, "That man-bag is so stupid!"
