A brand of condoms, designed for "extra large" sized dicks... however, most often purchased by men who are barely above average and could have saved themselves the extra five bucks... mostly with the intent that it will slide off inside the receiving hole, resulting in better sensation, pregnancy and herpes.
Drugstore Cashier: OMG! He's so cute AND he just bought Magnum XL condoms... he must be huge!

Condom user *internal dialog*: damn I hope this shit comes off when I'm hittin' that ass... cause I know I ain't gonna feel nothin' in that torn up pussy if it don't
