Mask Trading 

The latest product forex exchanges are keen to introduce to investors during this pandemic crisis, especially when mask wearing is likely to remain mandatory or be strongly recommended long after the populations of most countries have been vaccinated.

During this year’s new lockdowns, a number of bogus companies were charged for cheating gullible investors of over $10 million, by promising them an average of 20 percents returns in financing mask trading activities.

Mask Shock

The experience of being pleasantly surprised or shook at someone's real face when they remove their mask for the first time.

OMG my coworker took her mask off for the first time today and I had total mask shock. Her real face was so much prettier than I imagined!

Holy shit! I've been flirting with that guy for months and today the mask shock was real. He definitely isn't as hot as I thought.

Mask Off Challenge

It is a stupid and pointless joke revolving around Future's new top-hit - "Mask Off". This challenge was popularized by two guys, in which one guy in the back sings an A-Capella version, or tries to imitate the rhythm of the song, while another person sings the hook of the song. This challenge can be done with multiple people.

Daquan: Aye, man! You heard of that "Mask Off Challenge"?
Jaequan- Hell yeah, nigga! We got turnt up last night during that frat house party. We all was singing "Percocets, Molly Percocets", while one nigga in the back was just humming the tune.
Daquan: Aye man, we all 'bout that shit now. God bless Future for making such a beautiful masterpiece
Jaequan: True dat!

Mask Wave

When people from high-risk countries that have been hit by more than one wave of Covid-19 are so paranoid or petrified that they would wear more than one face mask each time—for instance, two masks for a second wave, and three for a third wave.

As Covid-19 second wave hits Singapore, third wave sweeps Delhi, and fourth wave grips Hong Kong, first-world countries are worried that their local supply of masks might be hijacked by a mask wave, as some extreme citizens take extra-precautionary measures to avoid getting infected.
