There is a global pandemic going on and you’re worried about a banter fest. I’m definitely not going to attend, don’t know about the rest of you, but I care about my life 

The act of roasting physics teachers and messaging the whole sixth form about why attending a banter fest during a global pandemic is an inadvisable thing to do.

Physics teacher: Hey guys I organised a banter fest for you next Monday. It'll be really fun!
Sensible person: There is a global pandemic going on and you’re worried about a banter fest. I’m definitely not going to attend, don’t know about the rest of you, but I care about my life
Physics teacher: Oh I'm sorry I didn't...
Sensible person: There is a global pandemic going on and you’re worried about a banter fest. I’m definitely not going to attend, don’t know about the rest of you, but I care about my life
Physics teacher: *Leaves school to go live in a remote Siberian village*

Defiantly 

to do something in a way that shows a disposition to challenge, resist, or fight.

more often just a misspelling of 'definitely' because the internet is full of dipshits

"She defiantly spoke out against the system."

"Their's defiantly sumthing rong with my phone, it keeps trying to incorektly fix my speling."

definitely forreal 

Phrase used to confirm that something is completely legit and totally believeable. Also means "I agree".

Allison: Yeah, he was so freakin' cute.
Angelique: Right, I'd hit that..twice.
Allison: definitely forreal.

most definitely 

A redundant modification of the word definitely, used by inarticulant athletes (oops, redundantcy alert) during television interviews to describe their agreement with a premise or event that is beyond definite, as if definite meant probably. Most probably used to convince viewers of their almost definite plan to finish the last 3 1/2 years of their college education, after scoring millions of bucks as a stud.

"We most definitely lost the game, since we only scored 10 points, and they hung 38 on us" (because sometimes, you win even though out-scored?).

defecately 

A more dignified way to say "Shit Yeah!" so you don't sound uneducated in the presence of others.

"Excuse me, fine sir, but would you perhaps like a spot of tea?"

"Oh, defecately, that would please me so."

definitely maybe

An annoying phrase that Andrew uses daily to describe something that may occur.

Me: "Hey Andrew, are you going to that party Saturday night?"
Andrew: "Definitely maybe."
