penguins freezing in antartica

The appropriate response to when someone takes off a jacket, sweater, etc. even though it is really cold either to display how "tough" they are or because they feel no cold. Especially when you are freezing yourself

Debrickashaw: Ahhh its not that cold
'Xebole: Dude its like 20 degrees outside and all i have is this vest
Debrickashaw: Stop being such a wimp <takes off coat>
'Xebole: what the hell, there are penguins freezing in antartica
