For research purposes 

An expression often used by men online who want to know the name of a certain video or person so they can store it in their spank bank.

It's synonymous with saying, "so I can fap to this later on."

Can anyone tell me the name of that girl in the video with the big boobs? For research purposes, of course.

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!
