A meme about the game Tetris that originates from a quote from the Classic Tetris World Championships of 2016. When a player named Jeff did a Tetris (clearing 4 rows at once), the host said this.
A mythical gym creature capable of moving seemingly impossible amounts of weight all while demonstrating below average form. Some say you can identify a Bro Jeff by seeing them front squat 315 lbs with a wide stance and overextending the knees.
"Jeffervescence" is the quality that someone named Jeff possesses when he is overflowing with enthusiasm, sparkling with charisma, beaming with light, exuding joy. The term was coined by Suzanne Whang (former host of HGTV's #1 show, "House Hunters") and was inspired by watching Jeff Vezain perform on stage with Gary Sinise's Lt. Dan Band.
As soon as he made his entrance on stage, grabbed the microphone and started singing, the audience was delighted and transfixed by his Jeffervescence.
