A variation on the "middle finger" obscene gesture. The wrist is cocked at a 90 degree angle and only the middle finger is extended straight in the air. Generally considered to be a more elegant way to express "<screw> you".
An extremely cancerous sentence posted on youtube comment sections of old videos so they can easily get likes. Usually, videos posted within the years 2005, to 2010 in 2017.
Yep, just post one simple "Who's watching in 2017" or whatever year you're in and you'll get likes in no time. About 10% of people hate this type of comment. The other 90% though, love it because it gets them likes and they don't have the skillz to become pro at making likable youtube comments.
A more elegant and dramatic version of giving "the bird" / middle finger. Possibly Scottish in origin. The wrist is cocked at a 90 degree angle, palm facing up, and the middle finger is raised straight in the air.
