Funny Birthday Wishes for Cousin in Hindi

जन्मदिन मुबारक हो मेरे प्यारे (और अब आधिकारिक तौर पर बूढ़े हो रहे) कज़िन! याद है बचपन में हम छोटी-छोटी बातों पर कैसे जानवरों की तरह लड़ते थे?

तुम्हारा जन्मदिन मुझे हमेशा उस शर्मिंदा करने वाले फैमिली फंक्शन की याद दिलाता है जिसके बारे में हम कभी खुलकर बात नहीं करते! मुबारक हो वह यादगार दिन!

इतने साल बीत गए लेकिन मुझे पक्का यकीन है कि तुम अब भी उतने ही बड़े शैतान बच्चे हो जितने तुम दस साल पहले थे! हैप्पी बर्थडे, सदाबहार बच्चे!

भले ही आज तुम्हारा जन्मदिन है और तुम स्पेशल महसूस कर रहे होगे, लेकिन हम सब दिल ही दिल में जानते हैं कि खानदान में सबका फेवरेट कज़िन तो मैं ही हूँ!

क्या तुम एक और पारंपरिक "केक तुम्हारे चेहरे पर" वाले सेशन के लिए तैयार हो, ठीक वैसे ही जैसे हम बचपन की बर्थडे पार्टियों में किया करते थे? जन्मदिन की शुभकामनाएं!

मैं सच में बहुत खुश हूँ कि हम रिश्तेदार हैं... ज़्यादातर समय तो मैं यही महसूस करता हूँ! जन्मदिन बहुत बहुत मुबारक हो, मेरे अनोखे और अद्भुत कज़िन!

हमेशा की तरह, तुम अपने जन्मदिन पर सारा ध्यान और सारी लाइमलाइट अपनी तरफ खींचने की पूरी कोशिश कर रहे हो! चलो ठीक है, आज तुम्हारा दिन है, जी लो अपनी ज़िंदगी!

मैं उम्मीद करता हूँ कि तुम्हें इस जन्मदिन पर बहुत सारे शानदार और महंगे गिफ्ट्स मिलें... जिनमें से कुछ अच्छे वाले मैं बाद में तुमसे उधार ले सकूँ! हैप्पी बर्थडे!

तुम एक और साल बड़े हो गए... क्या तुम उतने ही समझदार भी हुए हो? इस बात पर तो एक लंबी बहस हो सकती है! खैर, जन्मदिन मुबारक हो!

हमारे पागलपन से भरे बचपन की अनमोल और शरारती यादों के लिए तुम्हारा बहुत-बहुत शुक्रिया, वो भी क्या सुनहरे दिन थे! जन्मदिन मुबारक हो मेरे साथी अपराधी!

अब तुम्हारी उम्र हड्डियां चटकने वाली हो गई है, इसलिए बहुत ज़्यादा उछल-कूद करके पार्टी मत करना, वरना अगली सुबह पछताना पड़ेगा! हैप्पी बर्थडे, ओल्ड டைமர்!

याद है जब हमने मिलकर चुपके से दादी माँ की मिठाईयों का पूरा डब्बा साफ कर दिया था और इल्जाम छोटे भाई पर डाल दिया था? ऐसे ही किस्से हमारे रिश्ते को खास बनाते हैं!

मैंने बचपन में कितनी बार तुम्हारे कारनामों पर पर्दा डालकर तुम्हें मम्मी-पापा की डांट से बचाया है, उसका हिसाब कौन देगा? खैर, आज तुम्हारा दिन है, जन्मदिन मुबारक!

सारी मस्ती-मजाक और टांग खिंचाई अपनी जगह, लेकिन मैं सच में दिल से चाहता हूँ कि तुम्हारा यह जन्मदिन शानदार गुज़रे और तुम्हें दुनिया की सारी खुशियाँ मिलें!

चलो जल्द ही मिलते हैं और कुछ पुरानी यादें ताज़ा करते हैं और नई बनाते हैं, तब तक के लिए, जन्मदिन की ढेरों शुभकामनाएं और बहुत सारा प्यार!

Funny Birthday Wishes for Cousin in Urdu

تمہاری ہنسی ایسی چمکتی ہے جیسے چاندنی رات میں فانوس کا نور!

کاش تمہاری عمر کے ساتھ تمہاری شیطانیاں بھی ڈبل ہو جائیں!

تمہارے جینے کا انداز تو ایسا ہے جیسے کوئی گدھا سٹیج پر ڈانس کر رہا ہو!

سال بھر ہمیں پریشان کرنے والے انسان کو آج کیک کاٹتے دیکھ کر دل خوشی سے بھر گیا!

تمہارے بال سفید ہو جائیں پر تمہارے مزاح کا رنگ کبھی نہ اڑے!

تمہاری زندگی کا ہر دن ایسا ہو جیسے کھیر میں پڑا ہوا کشمش کا ٹکڑا!

آج تمہاری عمر کا عدد بڑھا تو خیال رکھنا دماغ کا عدد نہ گھٹے!

تمہارے ہونٹوں پہ مسکراہٹ رکھنے والے فرشتے کو سالگرہ مبارک ہو!

تمہاری شیطانی چمک آنکھوں میں ایسی ہے جیسے بارش میں چھپا ہوا سورج!

کاش تمہارے کیک میں ہر سال سو سو مٹھی والی موم بتیاں لگائی جائیں!

تمہاری خوشبو پھیلتی ہے جیسے کھٹائی والے گول گپے میں پانی کا چھینٹا!

تمہارے جوتوں میں چپل کی جگہ اب کیک کے ٹکڑے رکھ دوں گی!

تمہاری عمر بڑھنے کے ساتھ تمہاری ضد بھی بڑھتی جائے یہی دعا ہے!

تمہاری ہنسی کی گونج سے آج پورا گھر مہک اٹھے!

جیسے گرمیوں میں ठंडा शरबत ویسے ہی تمہاری زندگی میٹھی ہوتی رہے!
