Maccer 

A wierd Brit involved in some band who went around San Andreas. Seems to have a problem with not being able to stop 'giving himself a little bit'.

"Oh, for fucks sake Maccer! Leave yourself alone!"
"I can't help it, man!"

Macer 

One who is a dedicated fan of an American pop girl band, Megan & Liz, composed of fraternal twin sisters, Megan Mckinley Mace and Elizabeth Morgan Mace. Megan & Liz has garnered over 500,000 subscribers on their Youtube channel in a span of 4 years. Fans of Megan & Liz show their support by making themselves known as Macers.

Megan & Liz will be opening for Action Item on their upcoming, "The Stronger The Love" tour. I wonder if I'll meet a Macer or two at the Nashville show.

Mackerting 

Mackerting is the art of wearing a shirt one size too small. While more often then not this shirt will be collarless and will feature a v-shaped neck, Mackerting is not limited to v-necks. It is possible to Mackert in any type of shirt including, but not limited to: t-shirts, polos, button-downs, soccer shirts, basketball jerseys, and henleys.

Dude, is Jake juicing? His arms got huge overnight.
Naw, bro, he's just Mackerting; it's an optical illusion.

Red Mackerel 

A obvious mistake made intentionally for your boss to discover. Making your boss feel useful and allowing other mistakes to go unnoticed.

Put a Red Mackerel in that report so we don’t have to redo the whole thing.
