"Slap on" is a phrase that means to apply or put on something quickly and casually. It can be used in a variety of contexts, but is often used when talking about putting on sunscreen, lotion, or makeup. For example, someone might say "I need to slap on some sunscreen before going to the beach" or "She just slapped on some mascara before going out." It's important to note that "slap on" is a casual expression and may not be appropriate for more formal situations.
