- Crosses the Line Twice: His stage persona is deliberately played up to be a terrible, narcissistic person who sings about things like Helen Keller being the perfect woman, falling in love with an old woman and then her three-year-old granddaughter, giving head to Satan, a young boy named Adolf with all of the mannerisms of Adolf Hitler, and a barbeque hosted by the Ku Klux Klan. But it's okay, because it's hilarious.
- And satirical.
- Dude, Not Funny!: After making a tweet making fun of people named Hunter, Bo saw that there were a large number of people that got offended. He then expressed sincere apology and regret and even started personally tweeting Hunters with apologies.
- The reason he doesn't do "Klan Cookout" or "Perfect Woman" live anymore. He's said that he worries about the latter being used to make fun of a real-life deaf girl.
- Ear Worm: Most of his choruses; "Words Words Words", "Oh Bo", "Love Is...", etc.
- Epic Riff: The piano riffs of "Art is Dead" and "Oh Bo".
- The piano riff of "Art is Dead" has gained some fame by itself, and people were quick to note when Bo began playing it in "Playing Piano Gets You Laid", a video collab with College Humor.
- Freud Was Right: While reciting a story about how he saw "the biggest dick", Bo reenacts the scenario and uses his microphone as a stand-in for the penis.
- Genius Bonus: "What's domain, domain range? / A kid with too much in his pants". In math, domain is expressed by x, while range is expressed by y—the joke here being that said person is "XXY", which is the chromosomal makeup for a hermaphrodite.
- Growing the Beard: Seems to have happened around the time of Words Words Words. He's expressed embarrassment and dislike of much of his work prior to that period, which was more based around shock value for the sake of shock value rather than making a satirical point.
- Harsher in Hindsight: His "racial humor" skit had its effect amplified with the racial unrest that has happened since, with the shootings of several young African-American males as well as the Ferguson riots. Bo really meant it when he said whites and blacks were destined to fight forever.
- Hilarious in Hindsight: In Welcome to YouTube, he says that "most of the best YouTubers are either Asian or they're gay, so there's an untapped YouTube celebrity and his name is George Takei." While he's not so much specifically a YouTube celebrity, but since the song's debut, Takei has gained a huge internet following.
- Signature Song: "My Whole Family..." was the song that propelled Bo to his first bit of stardom, although "Oh Bo" is seemingly this as of late, considering the unanimous approval and participation it gets at live performances.
- Squick: The last few lines of "Sunday School":
I'm gay for Jesus
Fill me with Your grace
Pour Your love all over me
But please aim away from my face
- What Do You Mean, It Wasn't Made on Drugs?: The music video for "Words, Words, Words". Boy howdy.
- Special Effect Failure: Very clearly invoked.
