thonking 

An urban slang word which means a distorted, zoomed in or modified version of the "thinking" emoji. Often said or used in a moment which requires deep thought, or just as banter and on random occasions. Normally when said verbally your index and thumb make a shape that resembles a Nike logo and you hold that sign under your chin, as in the original "thinking" emoji.
