(In the seminal-ejaculation zone, so not to everyone’s taste.)
It started with a report on ADS-L from Wilson Gray thst Urban Dictionary had an entry for spray and pray conveying (of males) ‘engage in unprotected sex’. I haven’t found that entry, but this one’s close:
spray and pray: have sex with a lady w/ no protection and pray for no children. OMG i just fucked that bitch and left a load. I pray there are no little hommies to become of this. by BamMaster April 14, 2003
The expression has the ejaculatory V spray, a metaphorical usage ultimately grounded in (a) a V of liquid flow (intrans. The water sprayed onto the deck. trans. We sprayed the water onto the deck.), extended to (b) a V denoting a flow of bullets from a submachine gun, assault rifle, or the like; (c) a V denoting specifically a flow of urine from a penis; (d) a V denoting specifically a flow of semen from a penis; (e) a V denoting the dissemination (spread or distribution) of information from some source.
To the Vs in (a)-(d) there correspond product or result Ns spray; sexual spray is then a SquirtJet item like spurt, shower, squirt, jet, spew in a posting of mine yesterday.
Meanwhile, the whole expression spray and pray refers to indiscriminate or unconstrained spraying (in one of the senses (b)-(e)) accompanied by a merely hopeful or wishful attitude towards the consequences or results of the spraying.
