Basically the same context as a weeaboo, but with America. It is when people pretend to be American or of American origin (making themselves look like complete asses) usually the dead giveaway is when they have a large collection of various rifles, empty beer cans strewn around their house, a jacked up diesel pick up truck and a trucker hat with an American flag printed on it.
Americaboo: Git'er dun!!! *Shotguns a beer*
Random: Mate, this is Scotland
Americaboo: Every country is America, you skirt twirlin' faggot. *Waves a rebel flag while shouting loudly*
