2) You totally missed out, Liz just had the best Headlong moment.

headsong 

A song that's ridiculously catchy for one reason or another and gets stuck in your head for a prolonged period of time. Headsongs can be in your head for the entire time straight, or just reoccuring instances - like hiccups. Fucking hiccups.

AJ: Dammit, man, this headsong is fuckin' killing me.
Mike: What is it?
AJ: The fuckin' Safety Dance. It's been stuck in my head off-and-on for weeks now.
Mike: Ha ha, loser... oh wait, damn now it's in my head!
