purposelessnessist

In the 21st century, two men, generically named Tony and Jack, realised their lives were unlike those whom surrounded them. Tireless efforts to endure through life's many battles, only one name came with no surprise, to describe their such lives.

They are simply, profoundly, whom have no purpose when alive, nor purpose when deceased, the un-cared for, the un-needed nor wanted, the purposelessnessist.

When one realises they have no purpose in life and no one cares about one and vice-versa

porpose 

when a man in a long-term relationship begins to slowly turn into a porpoise. Signs of this include spending a lot of time in the water, feeling uncomfortable on land, and looking increasingly dolphin-shaped (but without the beak).

Jenny began to suspect that her boyfriend might porpose soon when every single one of their dates involved swimming in the ocean.

For all intensive purposes 

Nonsense, it means nothing. Its what people say when they really mean to say "for all intents and purposes".

1. For all intents and purposes = Correct

2. To all intents and purposes = Correct

3. For all intensive purposes = WRONG! You should have paid attention in English class!

Purposeful Nippling 

Purposeful nippling is going after the nipples with a purpose like are you gonna bite them? You want to lick them? Or can I just get a nibble. Simply put, it’s going at the nipples with a purpose. As opposed to accidental nippling where somebody’s nipples end up in your face and you’re overwhelmed by the nipple and compelled to put it in your mouth and do something with it. See accidental nippling for this.

My pepperoni nipples inspired some purposeful nippling last night.
