My wife always vomits with force. It's never just "Blehgh" and a puddle on the floor. Exorcism s**t, *every* time. Last time she did it while laying on my side of the bed, and hit the far wall, the dresser, clean laundry, and the lion's share in our toy box.
Took three trips to clean up all the puke because I had to step out to stop feeling sick from the smell.
A very close second would be the time she had the flu and s**t herself in the tub, only losing because I was able to just hose it all away. The puke required *elbow grease*.
