Well, first make sure you have the latest version of Snapchat. Then, on the main screen, you'll usually find a plus sign or something similar to start creating a story. You can select the photos or videos you want to include, add any text or filters you like, and then hit the post button.
Well, typically a Snapchat story remains available for 24 hours. But sometimes, depending on your settings or special features, it might be a bit shorter or longer.
For an Instagram private story, you could use 'Giggle Gallery'. It makes it seem like a collection of things that will make people giggle. Another one is 'Smile Snippets' which gives the impression of short, happy moments.
You could name them 'Giggly Glaive' and 'Chuckles Cutlass'. The 'Giggly Glaive' gives an impression of a spear - like weapon that seems to have a jolly or comical nature. The 'Chuckles Cutlass' for a sword, makes it sound like it has a sense of humor, as if it would make you laugh while using it in battle.
Two names could be 'Laughing Lance' and 'Smiling Sword'. The 'Laughing Lance' gives the idea of a long - pointed weapon that seems to be in a good mood. It could be imagined that it makes a laughing sound when thrust forward. The 'Smiling Sword' is a simple yet effective name for a sword that might have a smiling face engraved on it or has some property that makes it seem friendly even though it's a weapon.
