So you’ve seen “PU” in a text, on Snapchat, or in a TikTok comment, and now you’re wondering whether it’s an old-school exclamation or brand-new internet slang. Actually, it’s both. Depending on the context, the generation, and the platform, PU can mean several different things. Below, we break down every common meaning so you’ll never feel confused again.
Quick Answer
First and foremost, PU classically works as an exclamation for something that smells bad — think “P.U., that stinks!” However, in modern texting and social media, people also use PU to mean “pull up,” “pop up,” and “pick up.” Ultimately, the right meaning depends entirely on context.
1. PU = “That Stinks” (Classic Meaning)
This is the original, decades-old use of PU. Typically, people use it as an exclamation of disgust when reacting to a bad smell. In fact, English speakers have used this expression since the early 1600s.
Example: “PU! Did someone forget to take out the trash?”
2. PU = Pull Up (Come Over)
Originally borrowed from hip-hop and urban slang, “pull up” means to show up at a location. Over time, people shortened it to “PU,” and now friends casually use it to invite each other over or to a hangout.
Example: “We’re at the park, PU if you’re free.”
3. PU = Pop Up (Message or Show Up)
In texting culture, PU can also mean “pop up.” Specifically, someone uses this version when they want another person to message them privately or start a conversation.
Example: “I’ll PU later tonight, we need to talk.”
4. PU = Pick Up
Before either of those newer meanings existed, texters used PU to mean “pick up,” as in answering a phone call. Even today, some people still use it this way.
Example: “Calling you now, PU!”
5. PU = Swipe Up (Snapchat & TikTok)
On Snapchat and TikTok specifically, users sometimes pair “PU 👀” with a story or ad to prompt followers to swipe up and check something out.
Example: “New drop is live, PU 👀”
6. PU as a Playful Reaction
Beyond its literal meanings, people often use PU jokingly or sarcastically among friends. Instead of reacting to an actual smell, they use it to call out something mildly annoying or funny.
Example: “You actually ate the last slice? PU 😂”
