Cheap plastic blocks that snap together. A cheap and inferior ripoff of Lego. Most mega blok structures are less stable than a jenga tower that's been in play for a very long time.
Simpleton: "Check out this awesome building I made. It's made of mega bloks."
Reasonable person: "Is it supposed to be in multiple pieces?"

"Lego" is one of those new-age waka phrases. People use it when they're hyped or pumped up. Instead of "lego", it's cooler to say "megabloks" cause that's a different type of building block.

You - "Psssh... megabloks fool..."

The new and improved "lego" (let's go). Trend-following, new-age hip-hop fans use "lego" when they get pumped... It's better to say "megabloks" because Megabloks are something different than Lego building blocks.
Waka fan - "Time to get hype! LEGO!!"
