A female vlogger who's vacuous videos emphasize her breasts at every possible opportunity in order to accumulate views. The video thumbnail will also contain a prominent picture of her breasts.
The actual video content and dialogue is typically dire. Many viewers will note in the comments that they muted the sound in order to increase their enjoyment of the video.
The term comes from a variation of the term "Youtuber," one who uses Youtube. We arrive at "Boobtuber," one who uses one's boobs to generate traffic on their Youtube channel, by substituting "Bob" for "You" in Youtube. This is also a clever play on words in that a "Boobtube" is also a ladies garment often sported by Boobtubers in their videos.
Boobtuber's videos are popular with young males who have strict (militant) parents that would severely reprimand them if they were found to be viewing dubious sites, whereas good wholesome Youtube is considered fine..."It's ok mom, it's only Youtube...etc etc"
"You're not watching that boobtuber again are you? She's clearly not an intelligent person"
