Excited Show Title! It's a title ending with one or more exclamation points! Some comedy movies show they're comedies by having an excited title! Lots of musicals have excited titles! Often just the exclaimed first name of the lead character! So many, that it's become a Discredited Trope!
Slightly less grating when the title is an actual exclamation! Like "Help!"
Compare Excited Episode Title!, Title Scream! See also Lucky Charms Title!
Durarara!! This is tongue-in-cheek — in an author's note, the author explains they were added simply to poke fun at the fact that his other works Baccano! and Vamp! both have exclamation points at the end. "Heck, why not add TWO this time?"
Full Metal Panic! and Full Metal Panic! The Second Raid. Subverted with Full Metal Panic? Fumoffu, which is more of a confused show title instead.
1970s British comic book Cor!! has two exclamation marks. Sister publications at IPC/Fleetway included Whoopee! and Oink! (humour titles like Cor!!) as well as Smash!, Pow! and Wham! (action titles that eventually all merged together). There was also the very short-lived horror title Scream!
Comic book artist Scott Shaw! always has his name spelled like this. So does Tracy Yardley!, as a tribute.
Democracy Now! — which is rather sedate due to the smooth jazz intro and Amy Goodman's soothing voice. The excitement is attributable to the political radicalism of the program's guests.
The band Los Campesinos!! takes this a step further by renaming the band members' last names Campesinos!, too. So you get Gareth Campesinos!, Aleksandra Campesinos!, and the like.
Sufjan Stevens has five excited song titles from his album Illinois. One that comes to mind is "They Are Night Zombies!! They Are Neighbors!! They Have Come Back from the Dead!! Ahhhh!"
When it was released on vinyl, a few tracks were retitled and made more excited. For example, "Chicago" became "Go, Chicago! Go! Yeah!" Of course, the cover of the album itself gives the title as Come On, Feel the Illinoise!
When his first album was rereleased, an exclamation mark was added to the title: A Sun Came!
The Aquabats! have a lot of excited titles. Notably every song on "Fury of the Aquabats!" and "Charge!!"

Cameo's "Word Up!" (later covered by Mel B and Korn)
Shania Twain loves these. Come On Over has four songs with exclamation marks in their titles, including her hit "Man! I Feel Like a Woman!" Up! has eight.
El-Creepo! — the name of Todd Edward Smith's solo project and its debut album.
Porno For Pyros combine this with a bit of Lucky Charms Title with the song "Good God's://Urge!". Oddly enough, the album it's technically the title track to is just called Good God's Urge.
Half Man Half Biscuit opined in "Third Track Main Camera Four Minutes" that "If ever an album title was in dire need of an exclamation mark, it surely had to be Frampton Comes Alive!"
Jazz pianist Jon Jang has a fondness for this. He's released CDs titled Self Defense!, Tiananmen!, and Never Give Up!
Speaking of jazz, Ornette Coleman's Something Else!!! and Tomorrow Is the Question!
Another jazz performer who enjoyed these was the late pianist Andrew Hill. He released albums named Judgement!, Andrew!!! and Compulsion!!!!!

The Swedish feminist party, Feministiskt initiativ ("Feminist Initiative") is properly abbreviated Fi. However, since they chose to put the lowercase i upside-down in their logo, most people use F!
In the Swiss city of Basel, there is an environmentalist party called BastA!, whose name is an abbreviation for "Basel's Strong (i.e. cool/awesome) Alternative". "Basta" is also an Italian interjection, common in colloquial German, meaning "enough!". The exclamation mark adds emphasis.
Big Shot!, the show targeted at bounty hunters in Cowboy Bebop.
