ストレスはっさん (ストレス発散)

A friend of mine wrote this in an email as a reason for going to karaoke (context: ストレス発散したい！) and of course the ストレス part is Japanglish for stress. The 発散 part means "let out [feelings]" or emit. So translitterated as something like releave stress. A super useful word when you're stressed.
