Froshdog 

A freshman, or new person, usually dumb or naive, who probably needs a lesson or two in the real world. These individuals are typically the number one targets of hazing and/or pranks.

Steven - "Hey Josh, What are you doing tonight?"
Josh - "I don't know man, probably going to get hammered drunk and throw beer cans at the froshdogs who moved on campus yesterday."
Steven - "Seems legit. That'll show them. Fucking Froshdogs."

frothdogging

The drinking of many cold frothies (beers) with your mates. Generally at the pub.

Steve: What you up to this Saturday arvo bro?
John: Dunno, probably frothdogging down the local mate. Gotta get a few schooners in.
