You know in movies, when there's a sex scene... the guy n the gal come together and without any hand-guidance or as much as a glance down it just glides straight in first time...

when you try this... this is "going for a hollywood"

Variation: "a spikey hollywood"

you went for a hollywood, (doggy style, not a good idea) you got it wrong.. it went in, but ... well... you get the idea. She screams, you realise, pull out, a small nugget of shit follows you out, you see it and throw up over her back.
