When a man is on the dancefloor grinding with some bitch and he gets a boner. The man then takes his penis and pulls it upwards in his pants and buckles it under his belt so there is no buldge and no awkwardness with the bitch... so you can take her home and fuck her.
same as definition...it happens to me all the time and has yet to fail!! i love the german tuck!!
