LOLCODE is an esoteric programming language inspired by lolspeak, the language expressed in examples of the lolcat Internet meme. The language was created in 2007 by Adam Lindsay, researcher at the Computing Department of Lancaster University. The language is not clearly defined in terms of operator priorities and correct syntax, but several functioning interpreters and compilers exist. Read more on Wikipedia...


Example from the web:
HAI 1.3 OBTW Author: Logan Kelly (logan.kelly@gmail.com) Github: https://github.com/LoganKelly/LOLTracer TLDR OBTW prev is the number used in the randin function. I had to declare it in global scope so that it would retain its value between calls to randin. TLDR I HAS A prev ITZ 0 I HAS A rand_max ITZ 104729 OBTW Equivalent to C's rand() function, except returns a number in the range of 0 to rand_max. TLDR HOW IZ I randin I HAS A a ITZ 33083 I HAS A c ITZ 67607 prev R MOD OF SUM OF PRODUKT OF prev AN a AN c AN rand_max FOUND YR prev IF U SAY SO BTW Returns a random number within the range of 0-1. HOW IZ I rand_onein I HAS A rand_num ITZ I IZ randin MKAY rand_num IS NOW A NUMBAR I HAS A rand_max_float ITZ MAEK rand_max A NUMBAR FOUND YR QUOSHUNT OF rand_num AN rand_max_float IF U SAY SO OBTW Equivalent to C ceil() function. Returns the next largest integer for the given number. TLDR HOW IZ I ceilin YR num I HAS A int_num ITZ num int_num IS NOW A NUMBR BOTH SAEM int_num AN num, O RLY? YA RLY, FOUND YR num OIC DIFFRINT num AN SMALLR OF num AN 0, O RLY? YA RLY int_num R SUM OF int_num AN 1 FOUND YR MAEK int_num A NUMBAR OIC DIFFRINT num AN BIGGR OF num AN 0, O RLY? YA RLY FOUND YR MAEK int_num A NUMBAR OIC IF U SAY SO OBTW Convert a number to hexadecimal. This is returned as a string. TLDR HOW IZ I decimal_to_hex YR num I HAS A i ITZ 0 I HAS A rem I HAS A hex_num ITZ A BUKKIT I HAS A decimal_num ITZ num IM IN YR num_loop rem R MOD OF decimal_num AN 16 I HAS A hex_digit rem, WTF? OMG 10, hex_digit R "A", GTFO OMG 1
Example from Riju:
HAI 1.2 VISIBLE "Hello, world!" KTHXBYE
Example from hello-world:
HAI CAN HAS STDIO? VISIBLE "Hello World" KTHXBYE
Example from Wikipedia:
HAI 1.2 CAN HAS STDIO? IM IN YR LOOP UPPIN YR VAR TIL BOTH SAEM VAR AN 10 VISIBLE SUM OF VAR AN 1 IM OUTTA YR LOOP KTHXBYE
