Local social climber Mavis Lim reportedly achieved a state of biological peak today after successfully mentioning her son’s "elite" Commando status for the 400th time.

The 54-year-old housewife has spent the last eighteen months weaponising her son’s red beret to psychologically dismantle every other mother at the wet market.

Witnesses claim Lim’s face contorted into a mask of pure, unadulterated arrogance while she mocked a neighbour whose son was merely a "chao recruit" in a support vocation.

"My boy very siong one, jump plane every day, not like your son PES C storeman, everyday shake legs in air-con office," Lim boasted while aggressively brandishing a frozen pomfret.

"Even his field pack heavier than your husband’s entire future, you know or not?"

Military experts suggest that the psychological high of bragging about a son’s unit is the only thing keeping Singaporean parents from realising their children are just underpaid landscape gardeners in camouflage.

"Wah lau, her wayang is next level sia, her son only clerk at Hendon Camp but she talk until like he killed Bin Laden," noted a disgruntled neighbour.

Lim was last seen trying to stitch a "Guards" tab onto her own fake Gucci handbag to assert dominance before mahjong.
