How to Use Pickup Lines for Sisters

Whether you are teasing your actual sister or using the twin-sister classic on a crush, these seven habits keep it funny and warm.

• Know which sister you mean. Lines for your actual sister are wholesome banter. The twin-sister jokes are for crushes. Mixing them up is the fastest way to make a family dinner weird.
• Keep it kind. Sibling teasing works because it comes from love. Never use lines that actually hurt: stay on the playful side and watch her laugh.
• Use the twin line with a smile. The classic Do you have a twin sister? works because it is cheesy and confident at the same time. Say it lightly and let her enjoy the joke.
• Deliver at the right moment. Family dinners, car rides and random moments at home are perfect for sibling lines. Save the crush lines for a fun, low-pressure conversation.
• Follow up with sincerity. After the laugh, say something real: you mean a lot to me, or I am proud of you. That is what makes the joke land as love.
• Do not overdo it. One good line is a highlight, ten in a row is a stand-up set. Use one, enjoy the laugh, move on.
• Keep everything wholesome. Sibling humour should stay 100 per cent clean. The funniest lines are the ones everyone can laugh at together.
