Instawhore 

Generally females in the age group of 12-17 who participate in the social medium which is familiar to hipsters and food fanatics: Instagram. Instawhores compete against each other to take the most revealing photos of themselves. These photos are usually followed-up by numerous amounts of hashtags (such as '#Swag' and '#YOLO').

Jess: Hey Krystal, let's have a competition to see who can take the most amount of pictures of ourselves with barely any clothes on before our accounts get reported.

Krystal: Oh my gosh! That would be so awesome! We're gonna be such Instawhores. YOLO!

Instasham 

The social media platform that provides absolutely no true information about an individual, just the fabricated existence that the vacuous Vunts want to project to the rest of the inane sycophants that populate the site. #GiveMeAttention,
#MyBestVuntishLife, #Narcissist

Katie spent the last hour and a half trying to get the angle just right to hide her double chin and to catch the light just right making her cheeks glow and her puckered lips look like a lubed anus...... Ste just slapped his cock a few times and sent a dick pic back. The quintessential exchange on Instasham.

Instahate 

When you instantaneously or spontaneously know you hate someone or something.

I was overcome with instahate the moment I saw my ex's newest conquest.

I instahated her the second our eyes met!

Instawhore 

Someone who posts too frequently on social media and thrives on the attention they get from likes, comments, shares and follows. Instawhores may see themselves as influencers.

There's another post from Kate; she's such an Instawhore. You don't have to post a picture every minute of the day like an Instawhore.
