Supercentre 

Often misspelled as Supercenter

A supercentre is a big-box store, also known as a superstore or megastore, and is a physically large retail establishment—usually part of a chain. The term supercentre sometimes also refers, by extension, to the company that operates the store.
In essence, a supercentre is a supermarket and a department store, under one roof. The result is an expansive retail facility, carrying a wide range of products; these products include a full grocery line and general merchandise.
In theory, a supercentre allows customers to satisfy all their routine shopping needs, in one trip.

1. Later, I’m gonna go shopping at Walmart Supercentre.
2. Usually, I find everything I’m looking for, at a Walmart Supercentre.
3. I don’t like Walmart! Kmart Supercentres are way better!

Superficticial 

A person who does something only for sake of appearance, and keeps a piece of evidence to create or imply a false narrative.

Taking credit for actions that were not genuinely performed is a common type of narcissistic behaviour that is both superficial and self-aggrandizing. In the age of social media and selfies, such behaviour has become rampant.

I can't believe how superficticial those tourists were. They wore hiking attire and took photos in front of the mountain, but made no attempt to climb it.

She is so superficticial that she had the nerve to show up only at the end of the project and still posed for a group photo as if she had done as much as the rest of us.

She is such a neglectful mother but takes one photo each day of her child smiling to make it seem like she is a good parent. I hope her child doesn't grow up to be so superficticial.
