"Haha, you stupid WIDOW with young children, you were WIDOWED! How stupid can you be? And then you found a new relationship (SLUT), and then one time he was frustrated with your stupid kids! I can't believe how stupid you are!"
Chantal trying to use someone's status as a widow(er) as some kind of "le epic pwnage" is just another reinforcement about how she measures the worth of other people, more specifically women, and is another open window into her worldview.
It's again crystal clear Chantal's sense of worth is not based on food intake or material goods: it's based on having a man. Chantal has never gone long without a man, and even during the brief single beezin' arcs we know (or she claims) that she was actively dating "African continent folk" on Tinder. Most of Chantal's most famous stories involve a man of some kind, even dating back to when she was 15 and "dating" a 20+ year old pedo. Don't remember if Chantal has ever told a V-card story (or if that one was it) but she strikes me as one of those naturally psycho girls that lost it at 12.
If Chantal knows a haydur is single, or thinks they are (probably because they don't base their personality around their SO) she will use "you're just sad and jealous because I have a MAN!" as a response. She is unable to comprehend that someone can be happy while single, and her thinking is so black-and-white she can't comprehend that someone can be happy single while sometimes feeling lonely. If she thinks or knows they aren't single, she wants to find a way to cut that man's image down. Most people don't even remember that FFG once claimed her boyfriend "looked like lumberjack" but by Allah Chantal does, and so she uses that to (try and) make fun of FFG.
A spouse dying is rarely the other's fault, and people from all walks of life die of ODs (not just white trash like Chantal) and Chantal knows this, but Yaba getting widowed means she, at least at one time, lost and was without a man while Chantal had one, and therefore her worth is
ZERO!
