Fourth revival of ska music (the original being in jamaica in the late '60s, second wave or two-tone surfaced in the late '70s, and third wave hit in the late '80s and early '90s).

Many claim that the fourth wave is imminent, ready to appear anytime between now and the early 2010s.

Others claim the 4th wave is already here, heralded by Tomas Kalnoky's band Streetlight Manifesto and side project Bandits of the Acoustic Revolution. (There is a streetlight manifesto song titled "riding the fourth wave")

A few weeks ago, no one had “cheugy” in their vocabulary . Now everything is saturated with the word. It’s in our heads. It’s in our homes. Everyone is asking: “Am I cheugy? Am I a basic ass bitch? Am I GUILTY of being cheugy?”

The proliferation of cheugy in the mainstream discourse can only be attributed to one source: mental terror. It’s an orchestrated psychological trap to make you question your tastes and interests in the eyes of others.

You are not a cheug. YOU’RE PERFECT!!!!

It is very suspicious that the cheugy mascot is a Minion, a literal cyclops, a deformed
yellow panopticon in overalls ... do not let the all-seeing eye to control you. Be vigilant. Resist cheugy psyops.

A term many ska fans debate about. Some insist that Christian Ska is fourth wave, though musically it is still third wave. Other think fourth wave is heavier, though ska of that type is called Skacore. Most believe fourth wave is being lead by Thomas Kalnoky's Bandits of the Acoustic Revolution. It is a fuller band, similar to Big Band music, though with a more folk-y Eastern European sound. Similar to Gypsy music.
Fourth Wave includes a larger horn section and string section.

The Fourth Wave of Ska comes after Third Wave, Two-Tone and first wave ska. Sometimes called Skash for ska and thrash, but isn't necessarily thrash. This type of ska is defined by bands like Streetlight Manifesto and Big D & The Kid's Table. Difficult to describe, it's like ska/punk/thrash/dub/metal.

The finger, the bird

The first wave was novel according to some people, but by the fourth or fifth wave, the media is starting to sound like imbeciles, and so are scientists, helath care workers, government officials, and everybody else trying to warn people over and over again about viruses, restrictions, and mandates.

The media can't decide if the coronavirus is in it's third or fourth wave.
