Spotify Pitch: what does the song mood "fierce" mean ?

[soundson]

hi everyone.

in the Spotify for Artists Pitch to their Editors prior rto a release one can choose moods of the song such as chill, energetic, happy etc..

i am wondering what "FIERCE" means.

can anyone describe and/or give examples of other songs sounding "fierce" as it's meant by Spotify?

and esp. does this coming song by opur project 5ON5 sound fierce ?
