Using the internet excessively to the point of addiction 'I've been butt munching all day'.

Some who engages in excessive butt munching is a butt munch, and they device they use is often a giant butt munching machine (a phone or an ipod is just a butt muncher).
That little butt munch has been butt munching on his giant butt munching machine for 3 days straight.
