Splinters often have knee-jerk responses to "I'm sorry, sweetie, but this isn't working anymore" and will reply with "Oh yeah, well, you're a whore"

Splinter is a part of a bigger whole and reminds you it is about the little things in life. It is a true-hearted and open-minded person. A great listener who also keeps an edgy tongue. Don't be misguided by his appearance. Though he's looking sharp on the outside, he is absolutely sweet on the inside and always willing to share his wisdom. You could say he is one of few, and if there was a pocket edition of Splinter you would always want to carry him around.
1. Omg, he's looking sharp, he looks like a Splinter!
2.
Person 1: He is a bit of a hard candy shell, soft nougat center, isn't he?
Person 2: Yeah, that's a Splinter!
