A portmanteau of belligerent and delicate, describing people who constantly talk mad shit, but flip out the moment someone calls them out on their bullshit.
Belicacy is usually accompanied by a super-bougie disposition unique to Southern women.
This bellicate bitch has been shitting on me all day - thinking she's hella funny - but the moment I call her out on her Louis bag, she wanna throw down.
"Belgicism" is the English word for "Belgicisme" (a French word). It's the little differences between the French which is spoken in France and the one which is spoken in Belgium.
Teachers don't usually teach "Belgicism" because the teach French from France.
In Belgium, people might say : "J'ai trouvé ce magnifique pyjama ligné" which means "I've found this wonderful striped pyjama" but in France, people would say : "J'ai trouvé ce magnifique pyjama rayé". So "Ligné" which means "Striped" is a Belgicism.
