Hangul syllable Ggwing

It is one Hangul syllable block, not a word-level translation.

Its parts are ᄁ + ᅱ + ᆼ: an initial tense k-like sound, the vowel in “we,” and final “ng,” as in “sing.” The spelling “ggwing” is a romanized pronunciation label, not a translation.

Hangul was created in 1443; the work Hunminjeongeum explained the new script in 1446. Hangul writes speech with consonant and vowel letters arranged into syllable blocks.

what does it mean when someone sends 뀡?

Alone, it is a syllable, not a clear social signal.

Without surrounding Korean text or conversation, you cannot tell whether the sender meant a word, a sound, or something else. Ask for context if the intent matters.

how do i type 뀡?

On Dubeolsik, press Shift+R, n, l, d in that order.

Dubeolsik is a Korean keyboard layout. With a Korean Hangul input method (IME) active, Shift+R gives initial ㄲ, n plus l makes ㅟ, and d adds final ㅇ. Without a Korean IME, those keys stay Latin letters.
