That bounder pony have it coming. In real life these disgusting, disgraceful people thrive on hooking up and bedding females, exploiting them and then abandoning them as if they were trash to be discarded. It's impressive that Berry Punch could identify one of these unscrupulous individuals and repel his advances with a well-deserved punch in the face, all while drunk.
Ignoring for a moment that this is a fictional comedic situation thought up by my crazy mind. In reality responding with a punch is not even close to acceptable. It's still assault even if hes a sleazy dirtbag.
Actually not, She was with a different pony in the Sisterhooves social. Try and watch the sisterhooves social, and you can clearly see that the filly she is with there, is an earth Pony. While if you watch "Bridle Gossib", you will see Pinchy (The Unicorn in the comic), get pulled inside by Berry when she is scared ^^
