To beat someone with what is effectively no resistance on their part, to the point where you are "walking through" your opponent instead of actually fighting them.
He kept hyping me up like it was gonna be a big fight me if I came over there but he was so weak I could basically just walk through him.
To pass trough a non-smoking area with a lit cigarette. What makes a walk-through different from just smoking in the house (or wherever) is that the person makes an effort to get to the next smoking area as quickly as possible. In addition, hitting the cigarette nullifies the walk-through and thus constitutes "smoking in the house."
Rob: Hey I'm going out back, is it ok if I walk-through?
Marty: Yeah, go for it.

A phenomenon in film/television series, most notably streaming series, where the main premise is drawn out to such a point that it takes an entire season or more to get the parts of the series the audience is actually interested in seeing.
For example, if a series is titled "Surf Dracula," a majority of viewers would tune in expecting to see Dracula surfing by the first or second episode. However, the entire first season would instead be tedious padding and backstory before finally ending with Dracula surfing in the last five minutes of the season finale.
I watched "Smallville" on Netflix the other day. Dude, it was ten seasons of filler before he finally flew! Major Surf Dracula Syndrome!
