gentlesir 

Usually young white beta-males who live on Reddit or 4Chan. They wear fedoras with t-shirts. They open doors for women ("m'lady") or do other nice things not because they're polite people, but because they want to get laid.

Also related: talking about getting friend-zoned, loving V for Vendetta, libertarian politics, thinking they're the smartest person in the chatroom, basement dwelling, etc.

The gentlesir tipped his hat to m'lady and opened the door for her. She was just a random bystander and walked in without acknowledging him. He muttered to himself about how rude women were these days before checking the Reddit thread about anarchism.

Gentlesir 

1. "Gentleman," but with a pompous or sarcastic connotation.

2. Someone who tries too hard/awkwardly to be a gentleman or be noble, thus inspiring mockery and derision.

That's a bowtie of a fine gentlesir right there!

Few specimens in life are as cringeworthy as the self-righteous, neckbearded, fedora-wearing gentlesirs of reddit.

You address women by "M'Lady"? Mighty gentlesir of you!

Gentlefish 

The term gentlefish derives from the word gentleman. Gentlefish act as gentleman and are nothing short of the greatest group on the planet. Gentlefish often are often found in groups that consist of 2 or more good friends who identify as "brofish" ( these are most often males) they have to have known eachother for at least 9+ years. There are different subcategories of gentlefish such as the "Brofish" . Which is a term in the group to refer to one another. In the rare case that there is a girl involved in the group they can be referred to as a "Sisfish". One more term that is widely used is "oddfish", which means that one of the members of the group or an outsider is acting strange. Gentlefish are mere gentleman with nothing but eachother in the big blue sea, and it sure is a beautiful sight to see.

Kyle (first gentlefish): yo, brofish!! You up to anything??

Kyle: I mean, it's just us two
Payton: yeahhhh... but brofish foreva, right?
Kyle: on God's God

bed gentleperson

Someone that you both sleep with and go on dates with, but it's very casual and definitely not going anywhere. Fills the space between a friend with benefits/bedpiece and someone you are dating. Can be gendered as needed to bed gentleman or gentlewomen.

Last night I went out to dinner and hooked up with my bed gentleperson, but I think I'm going to set him up with my friend tomorrow.

Gentlefication 

Moving into a neighborhood in an effort to reduce crime, create harmony and build community. As opposed to "Gentrification," which changes neighborhoods by forcing out low income residents with high income folks seeking the next hip thing, Gentlefication helps long-term residents take back their neighborhoods, stabilize property values and build safe spaces for their children and grandchildren.

The local drug dealers were unhappy when the pastor asked his flock to move back into the neighborhood near the church to help in their gentlefication efforts.
