Beef joint 

1) A cut of beef that one may choose to eat with Sunday lunch.

2) The little hot bit towards the end, when smoking marijuana, that sometimes burns your lips.

3) A chubby elbow or knee (etc).

"Be a babe, and nip up to LidL to fetch us a beef joint for dinner"

"That beef just burned my fucking lips"

"Rosie, you seriously need to hit the gym and work off those beef joints".
