(n) A wagon with an incessant need to bring down the collective mood and general ambience of a group-chill, synonomous with Debbie Downer. Said wagon will "run over" normally enjoyable events which leads to fun turning into "roadkill".
Hey you want another drink?

Haven't you had enough? You're drunk. Stop drinking.

I was wondering how long it would be before the Whitcomb wagon would hit.
