Gak
A word used when you are unable to make yourself say anything else. A bit like a stunned silence, without the dignity of actually staying silent.
Leisha: OMG there's Justin Beiber!
Justin Beiber: Hey sexy lady.
Leisha: GAK !
Justin Beiber: Wow, you're a retarded fan who is too stunned to say anything because of my amazing hair.
Leisha: GAK !
