1
to show off to impress
to show something you have or can do so that people will be impressed
Vzorec užití:
to flex [something]
Častá chyba:
Learners sometimes think "flex" always means "to bend" because of older dictionary senses. In modern slang, especially online, it very often means "to show off". It is also easy to overuse this word in formal writing, where "show", "display", or "boast" are usually better choices.
Synonyma
show off (Neutral informal; slightly broader and older than the very current slang use of "flex".)
Antonyma
downplay (Means to make something seem less important, the opposite of drawing attention to it.)

2
to tighten a muscle
to make a muscle tight and hard, often to show strength or for exercise
Vzorec užití:
to flex [a muscle / body part]
Častá chyba:
Learners sometimes confuse this sense with the slang sense "to show off" and use it with people or things instead of body parts, e.g. *"He flexed his car"* in a physical sense. For the muscle meaning, the object should be a body part or muscle.
Synonyma
contract (More technical and neutral; does not carry the idea of showing strength in front of others.)
Antonyma
relax (Means to let the muscle become loose, the opposite of tightening it.)

to bend without breaking
to bend or move a thing a little without breaking it
Vzorec užití:
to flex [something]
Častá chyba:

Synonyma
bend (More general; does not always include the idea of not breaking or returning to the original shape.)
Antonyma
snap (Describes breaking rather than bending, the opposite outcome of safe flexing.)

an act of showing off
an action or thing that someone does to show off
Vzorec užití:
[something] is a flex
Častá chyba:
Learners may try to use "flex" as a verb here (*"That flexes"*) when native speakers usually use it as a noun in this sense: "That’s a flex." It is also easy to overuse in formal writing, where phrases like "show of wealth" or "display of confidence" are more appropriate.
Synonyma
boast (Usually refers to proud words; "flex" can be about things or actions, not only what someone says.)
Antonyma
humility (Humility is not trying to show off, the opposite attitude of making a flex.)

Vzorec užití:

Vzorec užití:
to flex [power / strength / influence]

Synonyma
assert (More formal and focused on stating or using power; "flex" is more vivid and often suggests a show of strength.)
Antonyma
