I think this came from a movie, where someone asked what mea culpa meant.
The first commercial use of ‘my bad’ that I can recall is by Cher in Clueless(1995). We were using it in 1985. It was actually preceded by ‘my fault’.
‘Sammiches’ is also way old. I was mispronouncing(actual not ironic) sandwich as a kid in the 70s. When it became part of pop culture, I don’t know. But the Bruh man character on Martin(1992-1997) was using it.
I propose we replace sammich with sangwich.
Yeah, I grew up with my mom referring to “peanut butter sandwiches” as “peener butter sammiches” (no snickering, now–she’s also called a “spoon” a “poon” :smack:). I hate peanut butter, so I didn’t pick up the first part, but after many years of resisting, I was finally assimilated into the *sammiches *camp, to the extent that giving it the standard *sandwiches *pronunciation feels awkward.
LMAO, my dad calls tampons “poons.” Like you, I have been assimilated and tampons have been refiled in my mental rolodex as “poons.”
If your mother asked my father to set the table, hilarity would ensue.
these drive me nuts:
focus (what, are you a camera?–can’t you just say concentrate… jeez)
proactive
my bad
“Um” to start any sentence, any forum or media, any time, any place! Make it go away!
Just kick him in the . . . errr . . .yeah.
Green.
Going green.
Thinking green.
Green this and green that.
“Amazing.”
“I was at Subway and got the meatball sub. The marinara was amazing. The guy who made my sandwich had the most amazing nose ring, and then I went to 7-11 and got the most amazing pack of Chicklets.”
Look, you skeezy twit, “Amazing,” means it filled you sense of reverential awe. If you’re that easily impressed, I suspect you could fill in for that guy in Flowers for Algernon. Try, “good,” or “nice.”
National Football League.
“Right now he’s one of the best receivers in the National Football League, and by the time he’s finished his National Football League career I wouldn’t be surprised if he’s looked at as one of the best that ever played in the National Football League.”
Abbreviations exist. Use 'em, dillweed.
ETA: Ok, it shouldn’t be “retired”, but c’mon announcers – stop using the phrase when calling a game. We all know what sport we’re watching, just say “NFL”.
Did she use it to stir Tang?
If you haven’t noticed that no one ever uses mild vocabulary anymore and only jump to the most extreme superlative they can get their hands on, you’re, like, the least observant guy EVER.
(yes, yes, it irks me as well.)
My second-grade teacher would smack you on the knuckles for that, especially the “nice.” We were explicitly forbidden from ever using it in a composition–she always wanted us to use a more descriptive word.
You may also wish to try, using, fewer, commas.
ETA:
… Maybe. 
The line often used in lame sitcoms: *in insulted tones *“I’m your mother, the woman who gave you birth”, usually said in conjunction with some inconsequential request, like would you mind splitting the tab?
I have been noticing this too. Very annoying. Did the league tell all the announcers they can’t say “NFL” this year or something?
A couple other sports phrases that should be retired:
True Freshman (is there such a thing as a False Freshman?)
Player X does Y as good as anyone in the league. (That’s supposed to be a compliment!?)
Brett Favre
“Well, I’ll discuss it with my DH when he comes home from work”. “My DS got an A+ in class”. “My DD and I are the same size.” :rolleyes:
In a discussion about sex, porn, or similar things … “I’ll need to see some photos to be sure of my response.”
… or similar words.
You and your designated driver are the same size? Handy if you throw up on your shirt I suppose. 
The phrase is used to distinguish a first-year college student from a redshirt freshman, who sat out his/her first season for any of various reasons (injury, academic difficulties, lack of opportunity for playing time). The redshirt freshman is a sophomore academically, but still in his/her first of four years of athletic eligibility.
