Ungenuine 

Originating from South East Asia, the term was originally used as an antithesis to describe a person/friend who wasn't "Genuine".

ie) Someone who merely acts like a friend but has a constant hidden agenda. A friend who is ungenuine would likely not keep in touch over a period of time only to hit you up out of the blue because it turns out they actually need something from you.

Ungenuine can also be used to describe someone who treats women with disrespect, fools around with multiple women in a given sitting at a given location (usually an aggressive type), untrustworthy, is overly sensitive about jokes, and is otherwise not a person who the rest of the group is fond of.

1. "Man, Lin just hit me up. I havent heard from that guy forever, he told me he was gonna be in town next week and asked if he could crash for a few days. That guy is so ungenuine.."

2. "Don't invite Tony to your kegger, he's so ungenuine.. He never pitches to bring any booze and always invites like 50 randos.."

3. "My bunk-mate came home last night with a girl, woke me up and tried to kick me out of the room so he could bang her on the bottom bunk.. That guy is such an ungenuine POS."

ingenuine

not yet an actual word. incorrectly used when trying to describe something that is the opposite of "genuine." usually confused with "Ingenuous" which means "gullible" and "ingenuity" which means "inventive originality". it is best to use the word "DISINGENUOUS" when you are vying for the antonym of "genuine".

Ingenuine is not a word.

Ingenuine

Meaning: adj. Not genuine; false; not authentic. Normally associated with persons, behaviours and experiences rather than items.

Etymology: Contrary to popular belief (google the term for examples), this is in fact a word, and can be cited as far back as the 17th Century:

1675 R. Burthogge Cavsa Dei 352 'A many false, supposititious, and ingenuine' Writings.

Source: Oxford English Dictionary online.

The word can be made by attaching the prefix in- (a variant of un-) to the existing word 'genuine', in parallel to in- + sincere, in- + compatible, in- + valid and so on.

Although it may often be confused with 'ingenuous', this is a simple malapropism and does not affect the validity of the word.

1. Bob's offer to buy Bill a present was ingenuine.

2. Her smile was ingenuine.

3. The tourist attraction gives an ingenuine experience of life in the 1500s.

Getting fucked by Microsoft. Paying 599 EUR for the retail version of Windows Vista Ultimate, 460 EUR for the hardware upgrades needed to use it and getting that lovely "This copy of Microsoft Windows(R) is not genuine." box after two weeks' use.

Person 1: 'I paid 599 euros for this sh!t and got to use it just two weeks'
Person 2: 'That's just unfair'
Person 3: 'But that's Microsoft's Ingenuine Disadvantage'
