The kind of cheap bottled wine that is only good for getting drunk. A portmanteau of smashed and Passion Pop - the cheap sparkling wine.
Can also be used in an verb or abjective form, when describing the activity of drinking smashenpop or the feeling obtained from smashenpop.
Mmm, Friday night and it's the right time for some smashenpop!
*giggle*, I'm feeling so smashenpopped.
Why don't we flog a bottle of champers and do some smashenpopping on the way to the party?
