Last Frinight, I got rip-roaring drunk and ran through my neighborhood naked.
Friday night. 'Frinight' should be used instead of saying Fri-day-night, because like saying 'mmm this cookie is cold-warm', that's really stupid. Also, Saturnight etc...
Person A: "Hey what are you doing Frinight?"
Person B: "Probably just staying in and orderin a Hot n Ready"
Person A: "Prostitute or pizza?"
Person B: "TBD"
