FaceTube 

Fictional online website a supposedly internet-ignorant person imagines everybody in cyberspace to be on all the time. Always used with "the". Possibly invented by Craig Ferguson. (Obviously, a combination of Facebook and YouTube.)

Craig Ferguson: Kids today don't know how to make a life-like corpse out of old sweaters. Nowadays they just download their corpse out of the Google or the FaceTube or something...

FaceTune

An app commonly used for editing substandard selfies. More notably, an incredibly effective and obvious way of letting the world know you need to 'tune' your 'face' in a hopeless effort to appear more attractive to the fake followers you purchased on Instagram.

I saved money by using FaceTune instead of Pro-Active!

Facetubing 

An enjoyable leisure activity that combines both Facebooking and Youtubing, Facetubing is a common pastime for the average bloke who spends half of his day in front of a computer. Any simpleton can be on Facebook and Youtube at the same time, but Facetubing can be achieved only by the most dedicated and resilient of fanatics.

Facetubers can be expected to constantly visit Youtube and Facebook ever so often in between doing actual work. At an advanced level, they may also exhibit a tendency to seek increased engagement by employing both desktop and mobile devices simultaneously.

A usual sight in the office when your peers have less than nothing for the day.

Wong said he was really busy with a project but was actually Facetubing all afternoon.

Facetubing 

Verb.

Facetubing is the act of using the internet only for Facebook and Youtube. This is recognized as a complete waste of time as no one has anything important to say on Facebook and watches clips on Youtube that have no importance or value. In some extreme cases this is an addiction where most people no longer visit any other websites besides Facebook and Youtube.

Person #2 "She's facetubing."
