interjection. A remark, generally thought of as southern slang, that is derived from the word "Well" and also used in its stead in order to lead one into another sentence that may continue a paused conversation/story or be used to signify the conclusion of one. Where as pronunciation of "Well" can be drawn out, "Whelp" is strictly pronounced very quickly and with a slight rising-inflection.
a. Whelp, the barn is on fire, I lost my cell phone, and my girlfriend is cheating on me with a clown. Today's been so-so, I s'pose.
b. Yea, so I say to her "You better have my money, or Santa Clause might come to town, ON YOUR ARSE!" *entire posse laughs , and suddenly a the story-teller's wife walks into the bar, brief pause as everyone looks at her* Whelp, time for me to getting home I s'pose.
(Robin is caught in bed with another man by Batman)
c. Robin: I guess the cat's out of the bag...
Batman: Whelp, that sure does explain a lot.
You know the saying, "If you can't run with the dogs, go sit on the porch with the rest of the puppies." It's kind of like calling someone a pussy. EX: Dude, you're a fucking whelp puppy, pussy. EX 2: Someone goes to a concert on a Sunday night and has work the next day, a REAL man would go, but a whelp a.k.a. pussy/puppy would stay home because he wouldn't "feel up to it".
