New words

Wordy Wednesday

I saw an article about the new words recently added to the Oxford English Dictionary. Here's a few I felt the need to point out (with my comments on them in pink).

• apols, pl. n. (informal): apologies. 
This seems very strange, but whatevs.
• cakepop, n.: a small round piece of cake coated with icing or chocolate and fixed on the end of a stick so as to resemble a lollipop. 
A delicious addition.
• derp, exclam. & n. (informal): (used as a substitute for) speech regarded as meaningless or stupid, or to comment on a foolish or stupid action. 
I have never even heard this word used.
• double denim, n.: a style of dress in which a denim jacket or shirt is worn with a pair of jeans or a denim skirt, often regarded as a breach of fashion etiquette. 
I had no idea this was even a thing. I would NEVER wear it (unless it was for a costume or something).
• selfie, n. (informal): a photograph that one has taken of oneself, typically one taken with a smartphone or webcam and uploaded to a social media website. 
I find this humorous for some reason.
• srsly, adv. (informal): short for ‘seriously’. 
OMG.
• twerk, v.: dance to popular music in a sexually provocative manner involving thrusting hip movements and a low, squatting stance. 
I blame Miley. Derp.
