“Did you see Steve is on TikTok now doing all these stupid dances with the zoomers? Looks like he got quaranteened hard.”
“Since the lockdown, all I do is eat junk food and watch tv. I haven’t showered in a week and the dishes in my sink have been there even longer. Love being quaranteened.”
“My husband is happy being quaranteened; playing Fortnite and CoD all day while I’m at my ‘essential’ job.”
