Like, you know, total Valley Girl talk is, like, totally associated with Poland, like, ohmigod. (And Polish fans have caught on with saying "Totalnie".)
Mochimerica as Nightmare Fuel. Seriously, we've seen him as a zombie, as worth 5million experience points to kill, and erasing someone from existence for trying to judo chop him.
Ukraine's "huge tractsof land". Even people who have never heard of the series would probably get the euphemism.
English version:
The dub makes a radical decision to apply the stereotypical, pretty offensive accents for each respective country, something that ADR directors usually try to avoid. This, along with the changes made by the translators that introduced new jokes, insults, and odd voices, resulted in some new memes, such as:
Romano in the English dub. The man is a memetic hurricane of insults. And all from one 2-minute video.
THIS WEATHERMAN IS PREDICTING A 99% CHANCE OF SHITSTORM, AND IT'S COMING RIGHT AT YA!
The video containing this line was out for less than a day before people started using it in case of Internet Backlash. (specifically, the backlash that came from that clip)
Which is actually an ascended joke from the fansubs.
"Things are turbulent!" "I'm lashing out at you!" "Things are turbulent!" "I'm lashing out at you!" "Things are turbulent!" "I'm lashing out at you!" ... fades into background as another character talks.
Soldier looking at Holy Rome's picture of Chibitalia: "Oh ho! Is this the painting of your little girlfriend, or boyfriend, or gender-neutral chibi-thing?" Awesome.
"Nice * insert Freud Was Right item here* ". Consisting of a song from Aqua Teen Hunger Force, and a character in a stripper pose wearing undies with a country flag on it, it goes from there. And it started with..."Nice Florida." Funny how America starts a lot of memes...
"England looks DEAD SEXY in a miniskirt!", which is an actual quote from Eric Vale, has started to become this. The retorts of "America looks dead sexy in a miniskirt" (also an actualy quote), and "IT'S A KILT, YOU WANKER!" are obvious tagalongs.
Crack shipping of Himaruya and the creator of Homestuck, Andrew Hussie. Popularized by artists Tannanana and Sclez on Tumblr. After another Tumblr user, himapapaftw, informed Hussie of the crack pairing by providing a link to the Hussieruya blog, many fans rushed to Himaruya's inbox to send him the same link. He has yet to respond.
In the new update of the Christmas Event (aka the 2011 Bloodbath), Austria gets tired of walking and Germany offers him his back to sit on. This branched out into fans pasting pictures of the characters onto the names of objects that sound like their name (example: "brussia", "cubacle", "austreea", etc.) and has become a meme in almost no time flat.
A minor meme on Tumblr, it came from a comment left by a member of the series's Hate Dumb on an anti-Hetalia stamp on Deviant ART. The comment found it's way onto dumbdeviantart, a popular blog that's Exactly What It Says on the Tin, and became a bit of a joke among fans on Tumblr.
ENGLAND'S PENSI SPERM WILL TURN YOU BRITIS. explanation

Paint it White
General pre-sub consensus: 'I have no idea WTF just happened.....BUT THAT WAS THE BEST MOVIE EVER!!!!'
In the English dub, France's Doctor Who reference was slipped in especially as a tribute for J Michael Tatum, who voices him. It's very popular with the English fans.
