FIB boat launch 

When an Illinois resident, usually on a Wisconsin lake, is unable to properly launch their boat. Side effects including backing up the line for everyone else, ruining their boat, or crashing their truck into the water.

“Yo what’s up with that dude that just drove his truck into the water?”

“He’s from Illinois. Classic FIB boat launch.”
