 “Me and my friends is going to the beach this weekend.”
“Me and my friends is going to the beach this weekend.” contains a grammar mistake. The correct sentence should be: "My friends and I are going to the beach this weekend." 

The subject pronoun "Me" should be replaced with the subjective pronoun "I". Also, the verb "is" is incorrect, and it should be changed to "are," which agrees with the plural subject "My friends and I."
